VOLTAMMETRY STUDY OF THE 2,4,6 -TRINITROTOLUENE CONVERSION INTO THE AMINE COMPOUNDS USING ZERO-VALENT IRON

The paper describes the use of voltammetry in monitoring the reductive process of 2,4,6 Trinitrotoluene(TNT) to amine compounds by zero-valent Iron. This method let’s us determine simultaneously the reduction of TNT and...

CHEMICAL CONSTITUENTS FROM DENDROPHTHOE FALCATE

The ethyl acetate extract of the roots and leaves of Dendrophthoe falcate yielded apigenin-8-C-β-D (2"-O-β-D-glucopyranosyl)-glucopyranoside. The isolated compounds were characterized by U V, I R, N M R and mass spectral...

INDIRECT SPECTROPHOTOMETRIC DETERMINATION OF NEOMYCIN BASED ON THE REACTION WITH CERIUM (IV) SULFATE

A simple and sensitive spectrophotometric method has been described for the assay of neomycin either in pure form or in pharmaceutical formulations. The proposed method was based on the oxidation of the studied drug by a...

LIQUID CHROMATOGRAPHY – QUO VADIS?

THERMAL ANNEALING KINETICS OF RADICALS FORMED BY THE RADIOLYSIS IN POLYCRYSTALLINE SOLID STATE OF ARGININE

The radiolysis with gamma radiation of arginine, in solid polycrystalline state, was performed at room temperature. The EPR spectra, recorded after radiolysis allowed the identification of three paramagnetic centers. A p...
