Extraction of Gold (III) Ions from Aqueous Solutions Using Surfactant Liquid Membrane abstract
Extraction of gold (III) ions from aqueous solutions by a polyamine type liquid membrane was investigated. Experimental results for the batch extraction of gold (III) ions by surfactant liquid membrane technique are presented. The effects of various parameters such as concentration of gold ions in the external phase, concentration of carrier, concentration of the internal phase reagents, pH of the external phase and the speed of agitation on the extraction rate were studied. Results showed that the use of this type of polyamine surfactant has a very good stability against both reducing-alkaline and acidic solutions and is suitable for this technique. The results showed that by proper selection of the extraction conditions, nearly all of the Au (III) ions present in a high concentrated feed solution was extracted within a few minutes.
