摘要
A new method for the separation of ion association complex of gold(Ⅲ) chloride rhodamine B by aqueous biphasic extraction system of n propyl alcohol (NH 4) 2SO 4 water was investigated.The experimental results indicate that the method can extract Au(Ⅲ) in hydrochloride medium.The extraction ratios of Au(Ⅲ) is 99.2%.The proposed method can separate Au from Fe,Al,Pb,Zn,Ca,et al base metals and was used for the separation of synthetic sample and the samples of anode slime and place gold.
