Recovery of zinc from electroplating wastewater using green emulsion liquid membrane

In this research study, removal of zinc ions from the industrial wastewater was investigated using green emulsion liquid membrane technology. The liquid membrane was prepared by using waste cooking oil along with the surfactant, SPAN 80 and the internal phase, sulfuric acid. The extraction percentag...
