Identification arsenic (V) by cyclic voltammetry and recovery of arsenic by electrodeposition

Abstract

This work is focuses in to develop an As(V) identification technique in an aqueous medium with KCl and KI as background electrolytes, in concentrations ranging from 1.33x10 M (1 mg/L) to 1.33x10 M (10 mg/L) applied in drinking water and 1.33x10M (10mg/L) to 1.33x10M (100mg/L) applied to identification to As in rejection water from capacitive deionization and Inverse osmosis. A technique of electro recovery of arsenic was developed by the application of a potential in acid solution in order to reduce As(V) and As(III) present in drinking and rejection water coming to mining activities, and process like Capacitive deionization and inverse osmosis.
