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.
