RCS作硫化剂有机阴离子对钨钼交换容量的影响

以RCS作硫化剂，HCI、CH3COOH分别作酸度调节剂，考察了含钼酸根的Na2WO4溶液中钼酸根生成硫代钼酸盐钼的硫代化率，以及溶液中阴离子Cl^-、CH3COO^-存在下。树脂D290、201-W对钨钼交换容量的影响．实验结果表明，钼的硫代化率都在99％以上；Cl^-存在下，树脂201-W对WO4^2-的交换容量为13．920mg／(mL湿树脂)；CH3COO^-存在下，树脂对WO4^2-的交换容量为75．725mg／(mL湿树脂).

The Effects of Organic Anion on Exchange Capacity of Tungsten and Molybdenum Using RCS as Sulfidizing Agent

Using RCS as sulfidizing agent, and HCl and CH 3COOH as adjust agent of pH, the yield of sulpho-complex of MoO 4 2- in Na 2WO 4 solution, and the effects of this two kinds of D290 and 201-W resins on ion-exchange capacity under existence of Cl - and CH 3COO - have been investigated. The experimental results show that the yield of sulpho-complex of MoO 4 2- can reach over 99%, and the ion-exchange capacity of 201-W resin on WO 4 2- is 13 920 mg/(ml wet resin)under existence of Cl -,and 75 725 mg/(ml wet resin)under existence of CH 3COO -.
