摘要

Methods for the determination of aminonitrophenols as dyeing agents are proposed, using carbon pasteelectrode (CPE) and boron-doped diamond film electrode (BDDFE) as working electrodes indifferential pulse voltammetry and HPLC with electrochemical detection. Comparison of bothelectrodes is given, concerning the applicable potential range, background current, reversibility ofelectrode reaction, repeatability and sensitivity of the aminonitrophenolsdetermination. Optimumconditions for the determination of aminonitrophenols in hair dye samples were found and selectedmethods are employed for the determination of 4-amino-3-nitrophenol in practical samples of hairdyes.
