| 摘 要： | P_(507)是一种良好的工业萃取剂,它能萃取镓族元素镓、铟、铊、萃取机理是P_(507)的P-OH基团的氢原子被镓族离子置换而形成螯合物。本文计算氧原子与镓族元素离子的重迭积分,从重迭积分估计其萃取规律,计算结果表明,其萃取次序是Tl>In>Ga,这个次序与实验结果是一致的。

| Abstract: | P_(507)is a good industrial extractant and can extract gallium family element such as, gallim, indium and thallium. Its extractive mechanism is that hydrogen atom in the P-OH group of P_(507)are exchanged by gallium family ion and form chelate compound. In this paper, the overlap intefral of oxygen atom and galliom family ion are calculated. From overlap integral its extactive rule is estimated and its extractive order is given by Tl>In>Ga. This order is identical with its experimental results. |
