Abstract
The methods for determination of the growth promoter 4-hydroxy-3-nitrobenzenearsonic acid (Roxarsone) in veterinary product and in poultry drinks have been developed using differential pulse voltammetry with carbon paste and Amberlite LA2 chemically modified carbon paste electrodes. Optimal conditions have been found for Roxarsone determination with nonmodified carbon paste electrodes with limit of determination being 3 μmol L-1. The sensitivity of the determination was further improved through Amberlite LA2 modification of the carbon paste with limit of determination being 0.1 μmol L-1. Modification also enabled preliminary accumulation of Roxarsone with the exchange of the supporting electrolyte.
