Abstract

A new composite carbon paste electrode incorporating bentonite (BentMCPE) was developed and used for extremely sensitive determination and electro-oxidative polymerization of azodyes using cyclic voltammetry. Lanaset Red 2B (LR2B) was selected as a model molecule for optimization of operational parameters such as amount of modifier, the pH of buffer medium, scan rate and dye concentration. Performance analyses showed that BentMCPE allows determination of LR2B, Acid Blue 113 (AB113) and Acid Yellow 17 (AY17) dyes as low as (6
