Synergistic Extraction for the Neodymium with PMBP,DAMP and TBPO |
| |
| Abstract: | This paper made an investigation on the synegistic extraction for Nd(???)from ' the medium of HClO4 with toluene solution of PMBP, DAMP and TBPO. The molar ratios and the equilli-brium constant of the extractive equation were determined. The mechanisms of synegistic extraction and the possible structure of extracted complexes were discussed. |
