摘要:测定了11种稀释剂对三烷基氧膦萃取草酸的分配比D的影响。结果表明,若按D的大小来排列,则芳烃类>烷烃类>卤代烃类。考察了无机盐MgCl_2、NaCl、KCl对萃取过程的影响,发现D随着盐浓度的增加先下降后上升,探讨了产生这一现象的原因。
It is discovered that upder the same conditions,the distribution coefficients ofoxalic acid D decrease with different diluents in the order of aromatic hydrocarbon,alkane,halogenated hydrocarbon.This ordcr is independent of the concentration of extractant in or-ganic phase.For the saIting-out agents used in extraction of oxalic acid,the effect is in thefollowing order: MgCl_2>NaCl >KCl.D decreases and then increases with increasing con-centration of saIting-out agents in aqueous phase,and the minimum D appears at0.5~1.0mol/L.
