Abstract

Efficient recovery of selenium from the dilute acidic solution is of great importance to the cleaner production of this scattered element. In order to overcome the bottlenecks of low recovery ratio and severe environment issues in conventional processes, an easy-operation electrochemical recovery process of Se was developed using low-cost stainless steel cathodes. It has been demonstrated that Se ions can be successfully electrodeposited, but the recovery ratio of Se is significantly limited by the low Se concentration. Consequently, a cylinder turbulent electrochemical reactor was employed for the extraction of metals from dilute solution (0.3 g/L Se(IV)). 97.6% selenium was successfully recovered within 90 min, nano-sized and mesoporous selenium product was also obtained due to the excellent mass transport effect. This mass transport-enhanced technique may serve as a promising alternative for metal and metalloid electrowinning.
