| Abstract: |
| The molar coordination ratio of complex formed by sorption of amino methylene phosphonic acid resin from mixed solution of thulium, ytterbium, lutetium was determined as 1.5∶1 through saturation volumetric method, equimolar series method and slope method. The absorption mechanisms include single molecular and double molecular chelate coordination. Based on IR spectrometry, the preliminary analysis indicates that nitrogen, oxygen atoms in functional group of APAR coordinate with Tm-Yb-Lu ion to form bonding and coordination compound. |
