【 摘 要 】

The extraction behavior of rare earth ion (RE (III)) using N, N'-dibutyl-N, N'-dioctyl-3-oxy-glutaramide from hydrochloric acid was investigated. The influences of hydrochloric acid concentrations, extract ant concentration, and temperature on the extraction distribution ratio were studied. The extraction mechanism was established and the stoichiometry of the main extracted species was confirmed by the slope analysis method.
