摘要
A study on liquidliquid extraction of palladium based on KIethanol in the presence of ammonium sulphate was performed.The results showed that PdI42- can be easily extracted into the ethanol phase.Common ions,such as Fe(Ⅲ),Al(Ⅲ),Zn(Ⅱ),Mn(Ⅱ),Ni(Ⅱ),Cr(Ⅲ),and Co(Ⅱ),could not be extracted into the ethanol phase and do not interfere with the determination of Pd(Ⅱ) at pH45.
