Optimum conditions for determination of genotoxic N,N-dimethyl-4-amino-4'-hydroxy-azobenzene (DAHAB) by differential pulse voltammetry and adsorptive stripping differentia! pulse voltammetry at a glassy carbon paste electrode (GCPE) have been estimated. Due to the fact that DAHAB molecule has two electroactive sites, its determination was based on electroreduction of the azo group and electrooxidation...
The use of glassy carbon electrodes (CPE) for the determination of tymol was studied. The amperometric detection with prior separation of tymol by HPLC is proposed. The optimum conditions have been found. The HPLC-ED limit of detection of tymol at +1.1 V v.v Ag/AgCl/3 mol L-1KCI in the mobile phase consisting of diluted Brilton-Robinson bufferpH 7-mcthanol 1:9 (v/v) was 2.9 x 10-7mol L-1which was...
