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).
