Sorption-catalytic determination of the nitrogen-containing organic compounds

Abstract

The influence of N-containing organic compounds (aliphatic, aromatic, and hetherocyclic) on the catalytic action of Cu(II) in the reaction of hydroquinone oxidation by hydrogen peroxide carried out on various surfaces has been studied. The procedures for the sorption-catalytic determination of imazapyr and cysteine on paper supports have been developed (the lower limits of determination are 1·10-3 and 5·10-4 M respectively) along with the procedures for the determination of cysteine and cystine on silica gel (the lower limits of determination are 5·10-5 and 8·10-5 M respectively).
