Determination of Antimony in Arsenous Oxide by Polarographic Adsorptive Complex Wave of Antimony(III)-Morin

Nanqiang Li

Abstract

In the base solution of 0.1mol/L H2SO4, a highly sensitive adsorptive complex wave of Sb (Ⅲ)-morin can be obtained by using single-sweep polarography. The detection limit is down to 2.0 x 10-9mol/L. It was used to determine antimony in arsenous oxide. The results are satisfactory. The mechanism of electrode processes were studied in detail.
