| Abstract: | The synergistic extraction of trivalent lanthanides from nitric acid solution by HBMPPT (4 benzoyl 2, 4 dihydro 5 methyl 2 phenyl 3H pyrazol thione 3) and TOPO in toluene, and the influence of temperature, concentration of HBMPPT, acidity on the extraction distribution ratio were studied. At the same time, the chemical composition of extracted complex and the extraction mechanism of extraction reaction were discussed. |
