Abstract

Methods for the determination of aminonitrophenols as dyeing agents are proposed, using carbon paste electrode (CPE) and boron-doped diamond film electrode (BDDFE) as working electrodes in differential pulse voltammetry and HPLC with electrochemical detection. Comparison of both electrodes is given, concerning the applicable potential range, background current, reversibility of electrode reaction, repeatability and sensitivity of the aminonitrophenols' determination. Optimum conditions for the determination of aminonitrophenols in hair dye samples were found and selected methods are employed for the determination of 4-amino-3-nitrophenol in practical samples of hair dyes.
