Abstract A sol-gel carbon ceramic electrode (CCE) without any assigned electron transfer mediator or specific reagents was used for the determination of fenitrothion by square-wave adsorptive stripping voltammetry. Fenitrothion strongly adsorbs on a CCE surface, which enables the development of facile electrochemical quantitative methods. Operational parameters such as pH value, initial potential value, and pulse frequency were optimized, and the stripping voltammetric performance was studied by using square-wave voltammetry. Square-wave adsorptive stripping voltammetry was used to obtain calibration curves with 2 linear ranges, 0.0050.1 and 0.150 M; the lower linear range was used to calculate the detection limit, 0.0016 M (5 min adsorption). The effect of interference species on the determination of fenitrothion was also studied. The inherent stability, high sensitivity, low detection limit, and low cost of analysis are the advantages of this sensor. The present method was successfully applied to the determination of fenitrothion in a commercial formulation and river water samples. Analysis of real water samples by using the sensor demonstrated the feasibility of applying the sensor to the on-site monitoring of organophosphate compounds.

Disposable electrochemically reduced graphene oxide-based (ERGO) screen-printed electrodes (SPE) were developed for the determination of total tetracyclines as a sample screening approach. To this end, a selective adsorption-detection approach relied on adsorptive transfer stripping differential pulse voltammetry (AdTDPV) was devised, where the high adsorption capacity and the electrochemical properties of ERGO were simultaneously exploited. The approach was very simple, fast (6 min.), highly selective by combining the adsorptive and the electrochemical features of tetracyclines, and it used just 10 μL of the sample. The electrochemical sensor applicability was demonstrated in the analysis of environmental and food samples. The not-fully explored AdTDPV analytical possibilities on disposable nanostructured transducers become a new tool in food and environmental fields; drawing new horizons for “in-situ” analysis.

Electrochemical behavior of atorvastatin (AT) and optimum conditions to its quantitative determination were investigated using voltammetric methods. Some electrochemical parameters such as diffusion coefficient, surface coverage of adsorbed molecules, electron transfer coefficient, standard rate constant and number of electrons were calculated using the results of cyclic voltammetry. A tentative mechanism for the oxidation for AT has been suggested. The oxidation signal of AT molecule was used to develop fully validated, new, rapid, selective and simple square-wave anodic adsorptive stripping voltammetric (AdsSWV) and differential pulse anodic stripping voltammetric (AdsDPV) methods to direct determination of AT in pharmaceutical dosage forms and biological samples. For the AdsDPV and AdsSWV techniques, linear working ranges were found to be 1.0 × 10–7–5.0 × 10–6and 3.0 × 10–7–5.0 × 10–6mol l–1, respectively. The detection limits obtained from AdsDPV and AdsSWV were calculated to be 6.55 × 10–8and 1.53 × 10–7mol l–1, respectively. The methods were successfully applied to assay the drug in tablets, human blood serum and human urine.

Electrochemical behavior of disopyramide (DPA) and optimum conditions to its quantitative determination were investigated using voltammetric methods. Some electrochemical parameters such as diffusion coefficient, surface coverage of adsorbed molecules, electron transfer coefficient, standard rate constant and number of electrons were calculated using the results of cyclic and square-wave voltammetry. All studies were based on the quasi-reversible and adsorption-controlled electrochemical reduction signal of DPA at about –1.60 V vs Ag|AgCl at pH 10.0 in Britton–Robinson buffer. This adsorptive character of molecule was used to develop fully validated, new, rapid, selective and simple square-wave cathodic adsorptive stripping voltammetric (SWCAdSV) method to the direct determination of DPA in pharmaceutical dosage forms and biological samples without time-consuming steps prior to drug assay. Peak current of electrochemical reduction of DPA was found to change linearly with the concentration in the range from 7.15 × 10–8 mol l–1 (0.024 mg l–1) to 1.43 × 10–6 mol l–1 (0.49 mg l–1). Limit of detection (LOD) and limit of quantification (LOQ) were found to be 5.65 × 10–8 mol l–1 (0.019 mg l–1) and 1.88 × 10–7 mol l–1 (0.064 mg l–1), respectively. The method was successfully applied to assay the drug in tablets, human serum and human urine with good recoveries at about 100%.

Abstract The interaction of macrocyclic compounds like crown ethers and UO22+ has been studied by electrochemical methods. A modified carbon paste electrode incorporating benzo-15-crown-5 (B15C5) was used to evaluate the electron transfer reaction of UO22+ by cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy. Electrochemical impedance studies showed that charge transfer resistance was less for the B15C5-modified electrode than for the plain carbon paste electrode (PCPE). On the basis of these observations, a UO22+-sensitive crown ether chemically modified electrode (CME) for trace analysis was fabricated and investigated in aqueous solutions. It was found that a 5 B15C5CME for UO22+ showed a better voltammetric response than did the PCPE. UO22+ could be quantified at sub-μg/mL levels by differential pulse voltammetry with a detection limit of 0.03 μg/mL. By differential pulse adsorptive stripping voltammetry, UO22+ could be quantified in the working range of 0.002-0.2 μg/mL, with a detection limit of 1.1 μg/L. Simultaneous determination of UO22+, Pb2+, and Cd2+ was possible. The method was successfully applied to the determination of UO22+ in synthetic, as well as real, samples; the results were found to be comparable to those obtained by inductively coupled plasma-atomic emission spectroscopy.

This thesis focuses on the optimazation of the electrochemical method, which characterizes products of untemplated nonenzymatic polymerization of 3',5' -cyclic guanosine monophosphate (cGMP) under conditions modeling prebiotic environment. An adsorptive transfer stripping techniques on carbon electrode and gel electrophoresis were used. The method was optimized on the model system of oligonucleotides located in solution of cGMP on carbon electrode, where DNA and RNA adsorb. This technique allows simple removing of interfering substances such as cGMP, which are not present in the original sample, but they do not adsorb on the surface of electrode or they adsorb weaker than oligonucleotides or polynucleotides. Analyses are based on the selective desorption of cGMP from the surface of the carbon electrode by the chemical and physical methods before the measurement of linear voltammetry itself. Detergents, such as SDS, Tween 20 and Triton x-100 with different concentrations and electrostatic repulsions of cGMP with different negative potentials on the carbon electrode were used for the selective desorption of cGMP. The selective desorption of cGMP was observed for all detergents and inserted negative potentials. Used methods were compared and the most effective detergent for selective desorption of cGMP was SDS. Desorption of oligonucleotides was minimalized by inserted positive potential on washed carbon electrode in 0,01% SDS in basic medium. This optimized method was used on electrochemical analysis of preliminary samples of untemplated nonenzymatic polymerization of 3',5' -cGMP and compared to the analysis of gel electrophoresis.

This thesis describes the application of macro, micro, ultra-microelectrodes and microelectrode arrays to the measurement of trace concentrations of nickel and cobalt in sediment and natural waters by adsorptive cathodic stripping voltammetric methods. In addition the measurement of tin by adsorptive cathodic stripping voltammetry in sediment and natural waters is discussed. Also, the application of macroelectrodes and microelectrode arrays to the measurement of lead, cadmium and zinc in sediment and natural waters by anodic stripping voltammetry is considered. In all cases the determination of the six metals was optimised by investigating the influence of various significant parameters, such as in-situ mercury plating, complexing agent concentration, scan rate, pulse height, accumulation time and potential, buffer concentration and pH. The results obtained for these investigations are discussed in this thesis

Differential pulse stripping voltammetry preceded by a non-faradaic preconcentration step is a very powerful technique for the direct determination of metal complexes, drug compounds and proteins. Small molecules like the amino acids can play a very important role in the biochemistry of living organisms. Despite their importance, these substances (except for cystine and cysteine) are generally not strongly adsorbed on mercury and /or do not possess any electroactive group in their molecular structure making their determination by direct electroanalytical techniques difficult or even impossible. These difficulties can be overcome by reacting these compounds with derivatising reagents (1). Initially here, derivatisation techniques for the determination of amino acids were studied. Methods are presented for the determination of tyrosine and histidine after coupling with diazotised sulphanilic acid (chapter 3) and for amino acids in general, and glycine in particular, as methyl or phenylthiohydantoin derivatives (chapter 5). Nanomolar levels of histidine were determined by accumulating the amino acid in the presence of an excess of copper(II) using the reduction peak of its copper(II) complex (chapter 4) for detection. The uses of polyamino acids as electrode modifiers were also studied and a method for the determination of copper(II) based on its accumulation at a hanging mercury electrode modified by adsorption of a polyhistidine film (chapter 6) and of hexacyanoferrate(III) after preconcentration on a copper modified polylysine film electrode (chapter 7) are proposed. As an offshoot of the diazo coupling derivatization of tyrosine and histidine, a method for the determination of copper(ll) by reaction with diazo-1 H-tetrazole (DHT) and accumulation of its complex on the HMDE (chapter 8) is presented.

This thesis describes the development of new adsorptive cathodic stripping voltammetric methods for reliable determination of some trace metals in biological and environmental materials on a glassy carbon mercury film electrode. In particular, the development of these methods involved selection of a suitable complexing agent for the respective metal ion studied, characterization of the electrode processes, investigation of factors affecting the voltammetric response such as concentration and pH of supporting electrolyte, concentration of complexing agent, accumulation potential, accumulation time and electrode rotation rate. Also, organic and inorganic interferences, linear concentration range, and detection limits were carefully considered. Furthermore, the analytical application of the method was demonstrated for each metal in biological and/or environmental materials, after optimization of the sample decomposition procedure. Some conclusions : the results obtained by the AdCSV method for the determination of tin in juices agreed reasonably with those obtained by atomic absorption method; the use of the adsorptive voltammetric technique after dry-ashing and UV treatment of the samples was successfully demonstrated for the determination of vanadium in standard reference materials such as urban particulate matter, peach leaves, apple leaves and bovine liver; and, the use of the adsorptive stripping voltammetric technique, after decomposition of samples by dry-ashing and UV treatment, was successfully demonstrated for the determination of molybdenum in peach leaves, apple leaves and bovine liver samples.

Adsorptive stripping voltammetry (AdSV) is a recent technique (initially named by Lam, Kalvoda and Kopanica in 1983) in which there is generally a nonelectrolytic accumulation (adsorption) of the determinand followed by a cathodic reductive or anodic oxidative scan. In this work, a hanging mercury drop electrode (HMDE) was used to accumulate several purine derivatives with and without the addition of Cu(lI) in a suitable buffer (usually Britton-Robinson, pH 7.5). In the presence of copper(lI) the copper(l) purine complex was usually accumulated at about -0.1 V. Some of the compounds studied (i.e dimenhydrinate, theophylline, guanine and azathioprine) can be determined as free compounds (i.e with no Cu(lI) added) after accumulation at potentials ranging from 0 to -0.2 V versus Ag/AgCI reference electrode. The determination of these compounds was made after optimising pH, buffer constituents, accumulation potential and accumulation time. The addition of Cu(lI) to these purines makes possible accumulation at shorter accumulation times , and improves the detection limits. For example, the detection limit of azathioprine in the presence of Cu(lI) is as low as 2x10-10 M. Both differential-pulse polarography (DPP) and DP-AdCSV (differential pulse adsorptive cathodic stripping voltammetry) were used in the determination of theophylline and azathioprine in their dosage forms (tablets). The relative standard deviations for the determination of the pharmaceutical purines in their tablets were 3.0%. 4.2% and 1.3% for the measured concentrations of dimenhydrinate(1.5x10-7 M) , theophylline(2x10-7 M) by AdSV ; and azathioprine(2x10-6 M) by DPP, respectively . Other purines (eg xanthine,1,3-dimethyluric acid and some methylguanines) did not give peak currents useful for their determination. The addition of Cu(lI) was necessary to obtain satisfactory peak currents for these purines. At low copper(lI) concentrations (Le.< 10-6 M), it is suggested that the purines form Cu(l) complexes which are adsorbed at the HMDE surface: Cu(lI) + Cu(O) + 2 L ~ 2 Cu(I)-L adsorbed.

This project focuses on the simple, fast and highly sensitive adsorptive stripping voltammetry detection of Nickel and Cobalt complexed with DMG and Nioxime respectively at a Reduced Graphene Oxide modified pencil graphite electrode in water samples. This research as well demonstrates a novel electrochemically reduced graphene oxide (ERGO)/mercury film (MF) nanocomposite modified PGE, prepared through successive electrochemical reduction of graphene oxide (GO) sheets and in-situ plated mercury film. The GO and graphene were characterized using FT-IR, HR-SEM, HR-TEM, XRD and Raman spectroscopy. The FT-IR results supported by Xray diffraction analysis confirmed the inclusion of oxygen moieties within the graphitic structure during the chemical oxidation step. Microscopic and spectroscopic analysis was used to confirm the stackings of graphene on the pencil electrode. The ERGO-PG-MFE, in combination with a complexing agents of [dimethylglyoxime (DMG) and Nioxime] and square-wave cathodic stripping voltammetry (SW-CSV), was evaluated towards the individual determination of Ni2+ and Co2+ respectively and simultaneous determination of both metals from the combination of DMG and Nioxime mixture. A single-step electrode pre-concentration approach was employed for the in-situ Hg-film electroplating, metal-chelate complex formation and its non-electrolytic adsorption at – 0.7 V for the individual analysis of Ni2+ and Co2+. The current response due to metal-ligand(s) complex reduction were studied as a function of experimental variables; deposition/accumulation potential, deposition/accumulation time, rotation speed, frequency and amplitude and carefully optimized for the individual determination of Ni2+and Co2+ and simultaneous determination of Ni2+ and Co2+ at low concentration levels (μg L-1) in 0.1 M NH3- NH4Cl buffer solution (pH 9.4) solution. The recorded limit of detection for the individual analysis of Ni2+and Co2+ was found to be 0.120 μg L-1 and 0.220 μg L-1 respectively, at an accumulation time of 120 s for both metals. The recorded limit of detection of the simultaneous analysis of Ni2+ and Co2+ was found to be 6.1 μg L-1 and 1.8 μg L-1 respectively. The ERGO-PG-MFE further demonstrated a highly selective stripping response toward all trace metal analysis. The testing of the applicability of graphene-based sensor and method in laboratory tap water samples was evaluated. This electrode was found to be sensitive enough to detect metal ions in the tap water samples at the 0.2 μg L-1 level for individual analysis and 0.001 μg L-1 for simultaneous, well below WHO standards.

The need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, portable and simple devices for remote sensing applications is therefore pivotal for early detection and the prevention of illnesses. Over the last two decades, adsorptive stripping voltammetry (AdSV) has emerged as a superior detection method over common analytical techniques due to its low-cost instrumentation, unskilled labour and ability to detect a wide range of analytes.

This work reports the use of a pencil graphite electrode (PGE) as inexpensive and sensitive electrochemical sensing platform fabricated by using electrochemically reduced graphene oxide (ERGO) in conjunction with an in-situ plated thin mercury film. For the first time the ERGOHgF-PGE sensor is proposed for simultaneous detection of cadmium (Cd2+), copper (Cu2+), lead (Pb2+) and zinc (Zn2+) using N-Nitroso-N-phenylhydroxylamine (cupferron) as complexing agent by square-wave adsorptive cathodic stripping voltammetry (SW-AdCSV). The technique is based on the adsorption of cupferron- metal ion complexes onto the surface of the ERGO-HgFPGE at 0.1 V for 60 s carried out in 0.1 M acetate buffer solution (pH 4.6). The synthesized graphene oxide (GO) and graphene nanosheets (GNs) were characterized using different analytical techniques such as FT-IR which confirms the presence of oxygen moieties embedded in the graphitic structure and further demonstrated by UV-Vis, validating the synthesis of GO

Carbon nanomaterials (CNMs), especially carbon nanotubes and graphene, have been attracting tremendous attention in environmental analysis for rapid and cost effective detection of various analytes by electrochemical sensing. CNMs can increase the electrode effective area, enhance the electron transfer rate between the electrode and analytes, and/or act as catalysts to increase the efficiency of electrochemical reaction, detection, adsorption and removal are of great significance. Various carbon nanomaterials including carbon nanotubes, graphene, mesoporous carbon, carbon dots exhibited high adsorption and detection capacity. Carbon and its derivatives possess excellent electro catalytic properties for the modified sensors, electrochemical methods usually based on anodic stripping voltammetry at some modified carbon electrodes. Metal electrode detection sensitivity is enhanced through surface modification of working electrode (GCE). Heavy metals have the defined redox potential. A remarkable deal of efficiency with the electrochemical sensors can be succeeded by layering the surface of the working electrode with film of active electro-catalytic species. Usually, electro catalysts used for fabrication of sensors are surfactants, nano-materials, polymers, carbon-based materials, organic ligands and biomaterials.
