Anodic Oxidation of Alkaline Sulfide Solution at a Low Potential

Ning Zhang, Wei Qing Han, Lianjun Wang

Abstract

The oxidation of sulfide was investigated at a potential of about -0.1 V, 60 °C and electrolyzation time of 48 h, the sulfide ions were oxidized to sulfur and polysulfide, and the predominant polysulphide was S22-. The behavior of the anodic oxidation was highly dependant on the applied temperature and the concentration of the sulfide ions.
