Microfluidic solvent extraction of zinc from sulfate solution was studied using di-2-ethyl hexyl phosphoric acid, D2EHPA, in sulfonated kerosene as diluent. The influence of different parameters on the extraction of zinc, such as extraction concentration, O/A ratio, contact time, saponification rate and the concentration of zinc in the aqueous phase were investigated and the conventional and microfluidic extraction were compared. Response surface methodology (RSM) was applied to optimize technological parameters of the conventional and microfluidic extraction process. Under the optimized conditions, the microfluidic extraction efficiency of zinc is up to 97.1%. It is better than that conventional extraction. Therefore, microfluidic solvent extraction can achieve high efficiency and low consumption of extraction process.
