Abstract

The theoretical description of prodigiosin pigment electrochemical determination, assisted by novel triazolic derivatives, reinforced by cobalt and nickel oxyhydroxides, has been described. It was noticed that both cobalt and nickel oxyhydroxides may serve as efficient electrode modifiers of prodigiosin electrochemical determination in neutral and lightly alkaline media. The electroanalytical process is diffusion-controlled. The oscillatory and monotonic instabilities in the system are possible, being caused by DEL influences on the chemical and electrochemical stages.
