摘　　要：The extraction mechanism of rare earth elements from chloride medium with sec octylphenoxy acetic acid(CA 12) in n heptane has been studied. The results showed that CA 12 could be applied to separation of Y from light rare earth mixture. The structures of the extracted complexes were deduced based on the IR measurements.The extraction mechanism of rare earth elements from chloride medium with sec octylphenoxy acetic acid(CA 12) in n heptane has been studied.
