Abstract

Acatalytic polarographicmethod for the determination ofmicrogramquantities ofCr(III) is developed based on the catalytic currents of chromium(III) in the presence of antipyrine in potassiumchloride medium. The procedure is applied for the estimation ofCr(III) in agricultural samples. Themethod is simple, sensitive and free from interference of manymetal ions.
