Separation Copper Ions from Aqueous Solution by Emulsion Liquid Membrane Using Novel PAMAMG4-1,2-Octenoxid Dendrimer as Carrier
Abstract:
PAMAMG4-1,2-octenoxid dendrimer was prepared and used as carrier in ELM to extract copper ions. The membrane was prepared by dissolving PAMAMG4-1,2-octenoxid dendrimer and Span 80 in chloroform. The internal phase is aqueous solution of hydrochloric acid. Effects of operating parameters such as carrier concentration, surfactant concentration, hydrochloric acid concentration in the internal phase, emulsification time and emulsification speed on the membrane stability were studied. In addition, the effect of carrier concentration, surfactant concentration and hydrochloric acid concentration in the internal phase on the extraction efficiency was also investigated. The results showed that PAMAMG4-1,2-octenoxid dendrimer is a suitable carrier for copper ions in ELM system.
