Abstract:

A series of complexing adsorbents is prepared by coating silica particles with linear polyhexamethylene guanidinium (PHMG) chloride followed by saturation with a number of sulphonated nitrosonaphthols reagents electrostatically retained by positively charged polymer layer. PHMG coated silica is hydrolytically stable even during treatment with 6 M HCl heated up to 50 °C. The adsorption of 1-nitroso-2-naphthol-3,6-disulfonic acid (nitroso-R-salt), 2-nitroso-1-naphthol-4-sulfonic acid (nitroso-N-salt), and 2-nitroso-1-naphthol-3,6-disulfonic acid (nitroso-K-salt) on PHMG modified silica was studi

Abstract:

Providing macroscopic magnetism in organic materials is a very complex but quite promising scientific problem. The need to create an organic magnet is due to a number of expected advantages, such as lightness, transparency, flexibility, ability to switch under the influence of light (magneto-optics), or chemical influences (sensors), creation of modern toners for digital printing, materials for chemical power sources etc. To understand the mechanism of biological processes, in particular, human thinking and DNA functioning may help to study the state of spin glass, biomagnetism, the mechanism

Abstract:

The azo coupling reactions of six five-membered ring heteroaromatic diazonium ions with 2-naphthol-3,6-disulfonic acid are investigated kinetically at various pH values. The dependence of the measured rate constants on the acidity of the aqueous reaction system is evaluated. It can be shown that the 2-naphtholate-3,6-disulfonate trianion reacts 4 × 108–8 × 108 times faster than the 2-naphthol-3,6-disulfonate dianion. The rate constants of the six diazonium ions vary by more than four orders of magnitude. The logarithms of the rate constants of all comparable diazonium ions correlate linearly w

<strong>Abstract:</strong>              In the present research, the reagent <em>N</em>, <em>N</em>-1,2-Phenylenebis (2-Hydroxybenzaldehyde) is synthesized by Schiff base reaction. Reagent is characterized by FT-IR and NMR. This reagent is coupled with Co (II) to get a monometallic complex. Another mono-metallic complex has been prepared by using 1-Nitroso-2-Naphthol as a reagent with Ni (II). The combination of these two will give a Hetero-bimetallic complex. This prepared complex is characterized by using FT-IR and Elemental analysi

Abstract Manganese is quantitatively retained by 2-nitroso-1-naphthol-4-sulfonic acid (nitroso-S) and tetradecyldimethylbenzylammonium (TDBA) chloride on microcrystalline naphthalene in the pH range 9.5–10.6 from large volumes of aqueous solutions of various samples. After filtration, the solid mass consisting of the manganese complex and naphthalene is dissolved in 5 mL dimethylformamide and the metal is determined by flame atomic absorption spectrometry. Alternatively, the manganese complex can be quantitatively adsorbed on TDBA–naphthalene adsorbent packed in a column and determined similar

Abstract:

Rapid photometric assessment of iron in blood plasma and serum by a simple procedure after the extraction of iron(II) complex with 1-nitroso-2-naphthol in the micellar phase of a nonionic surfactant at the cloud point upon heating (pH range is 4.5–6.3) is proposed. The procedure trueness was verified using a standard reference protocol using bathophenanthroline. The advantages of the procedure are higher sensitivity than the reference protocol: the limit of detection is 0.03 μg/mL, the limit of quantitation is 0.1 μg/mL, the determination range is 0.1 – 2.8 μg/mL (RSD 0.02–0.10).

Abstract:

The aim of this work was to develop a new kinetic spectrophotometric method for the determination of ibuprofen in pharmaceutical formulations. Ibuprofen was determined in an acidic ethanolic medium by monitoring the rate of appearance of 1-nitroso-2-naphthol, resulting from the displacement by ibuprofen of Co(III) from the tris(1-nitroso-2-naptholato)cobalt(III) complex. The optimum operating conditions regarding reagent concentrations and temperature were established. The tangent method was adopted for constructing the calibration curve, which was found to be linear over the concentration ran

Abstract:

This study reports the synthesis of five novel Schiff base heterobinuclear nickel(II) and tin(II) complexes. The heterobinuclear complexes were synthesized by the interaction of N,N′-ethylenebis(2-hydroxyacetophenoniminato) nickel(II) with tin(II) salts of 2,4,6-trinitrophenol, 1-nitroso-2-naphthol, o-nitrophenol, 8-hydroxyquinoline and 2,4-dinitrophenol. Characterization of these complexes was carried by physico-chemical techniques such as elemental analyses, conductivity measurements, magnetic measurements, infrared spectra and electronic spectral studies.
