摘要：
This work investigates the extraction of cadmium (II) from aqueous solution through supported liquid membrane system (SLM). A microporous polypropylene (Celgard 2400) film with tridodecylamine (TDDA) in xylene was used as a membrane phase. Cadmium chloride and hydrochloric acid was used as a feed phase, while ammonia solution was used as stripping reagent. Effect of concentrations of feed, strip solution, and carrier was investigated for the extraction of cadmium. The optimized concentration of Cd(II) and hydrochloric acid, carrier, and striping reagent solution were 1.33x10(-3) mol/L, 1mol/L, 30%, and 6mol/L, respectively. Ninety-two percent extraction of cadmium (II) was achieved under the optimized conditions. In this work, tridodecylamine has been used as a carrier for the first time for the extraction of cadmium ions from wastewater.
