摘要
本文系统地研究了二(1—甲基庚基)磷酸酯(DMHPA)-稀土(RE)萃取体系中凝胶态形成的条件,发现DMHPA的浓度、皂化度、稀土负载率等其它诸因素对凝胶的产生有一定的影响.
The conditions of the gel formation in the extracted systems containing [di (1 methylheptyl)]phosphoric acid (DMHPA) and rere earth ions were studied. It was found that the concentration and saponification percentage of DMHPA, the loading of lanthanide and some other factors have influence on the gelation in the above systems but the gel was not observed in the extracted organic phases containing Cu 2+ or Ni 2+ . 〖WTHZ]
