Abstract:

The electrochemical behavior of some hetarylated formazans introduced into the bulk of carbon-containing inks of thick-film screen-printed electrodes was studied. The compositions of complexes formed at the electrode surface were found, and their stability constants were estimated. It was shown that the modification of a carbon-containing, thick-film electrode with 1-(o-chlorophenyl)-3-phenyl-5-(6-methyl-4-oxo-pyrimidinyl-2)formazan improves its sensitivity, lowers detection limits for Pb(II), Cu(II), Cd(II), and Zn(II), and ensures high precision of the results of analysis.
