Abstract:
For the first time, new possibilities of using the DPPH• as a signal-forming oxidant molecule with potentiometric detection are shown. The CV method confirmed the presence of a quasi-reversible potential-determining system DPPH•/DPPH-H under experimental conditions. This fact makes it possible to use DPPH• as the model of the oxidizing agent for obtaining an analytical signal by the potentiometry method. The potentiometric approach makes it possible to obtain the value of the Nernst slope and the antioxidant capacity in one experiment. It consists of an antioxidant supplement and two consecuti

Abstract:
Potentiometric oxygen monitoring using platinum as the electrode material was enabled by the combination of conventional potentiometry with active prepolarization protocols, what we call active potentiometry. The obtained logarithmic transfer function is well-suited for the measurement of dissolved oxygen in biomedical applications, as the physiological oxygen concentration typically varies over several decades. We describe the application of active potentiometry in phosphate buffered salt solution at different pH and ion strength. Sensitivity was in the range of 60 mV/dec oxygen concentration

The speciation of Fe2+ and Fe3+ iron ions using the concentration cell potentiometric method has been developed. The determination and speciation of metals that have been used include potentiometry using comparison electrodes, selective ion electrodes, and voltammetry. The concentration cell potentiometric method has the advantages of simple equipment, the use of common metal electrodes, high selectivity, and relatively low detection limits. The method validation results for Fe2+ and Fe3+ ion speciation was LOD: Fe2+ 0.22 mg/L and Fe3+ 0.29, LOQ: Fe2+ 0.92 mg/L and Fe3+ 0.01 mg/L; precision (1

Abstract:
“Green” explosives are an important sub-family of explosives due to the banning of explosives based on heavy metals, such as lead azide and lead styphnate, according to the REACH list. A substitute to lead azide is potassium 4,6-dinitrobenzofuroxane (KDNBF) which is an alternative “green” explosive. Hence there is an upcoming need for analytical and quality control protocols for KDNBF. In this report is HPLC-UV/VIS, GC-FID and potentiometric titration evaluated for their suitability as methods for testing of KDNBF. The results implies that KDNBF can be analyzed by GC-FID, when dissolved in DMS

Abstract:
The structure of 25, 26, 27, 28-tetra(2-ethoxyaniline)calix[4]arene of cone (cL) and partial cone (pcL) conformations were optimized by PM3 of quantum chemical method. It has been found that cL structure is more stable than pcL conformation. The stabilization energies of protonation on four aniline-nitrogen atoms of both conformations of the ligand at 6-31G energy level, were obtained. The protonations process on the cL and pcL being 7 and 24 possible pathways, respectively, were evaluated. The basicity constants of partial cone conformation of 25, 26, 27, 28-tetra(2- ethoxyaniline)calix[4]are

Abstract:
The original objectives of this research project were to: (1) develop immunoassays, photometric sensors, and electrochemical sensors for real-time measurement of progesterone and estradiol in milk, (2) develop biosensors for measurement of caseins in milk, and (3) integrate and adapt these sensor technologies to create an automated electronic sensing system for operation in dairy parlors during milking. The overall direction of research was not changed, although the work was expanded to include other milk components such as urea and lactose. A second generation biosensor for on-line measuremen
