%X Through the methods of saturation, equivalent molarity and slope, the experimental results showed that the extraction ratio for Cyanex272 resin approached 3 and chlorine ions did not take part in the coordination reaction. The results by infrared spectroscopy also showed that Cyanex272 was single-polymer in extraction chromatography by which the amount of extractant was less than double-polymer in solvent extraction. The extracted compound was determined as REA_3. The adsorption-extraction mechanism by Cyanex272 could be expressed as RE~(3+)_((a))+3HA_((r))=REA_(3(r))+3H~+_((a)).
