用R1 CS作硫化剂 ,HCOOH、CH3COOH分别作酸度调节剂 ,考察了含MoO4 2 - 的Na2 WO4 溶液中钼酸根生成硫代钼酸根的硫代化率 ,以及溶液中酸度调节剂HCOO- 、CH3COO- 存在下 ,树脂D2 90、2 0 1-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 97%以上 ;HCOO- 存在下 ,2 0 1-W树脂对WO42 - 的交换容量为 75 .72 5mg mL ,CH3COO- 存在下 ,2 0 1-W对WO42 - 的交换容量为 96.70mg mL湿树脂
Using R1 CS as a curing agent, HCOOH and CH3COOH as acidity regulators respectively, the effects of molybdic acid and thio-molybdate in the solution of MoO4 2 - Effect of Resin D2 90,2 0 1-W on Exchange Capacity of Tungsten and Molybdenum in the Presence. The experimental results show that the molybdenum sulfurization rate is above 97%; in the presence of HCOO-, the exchange capacity of 2 0 1-W resin to WO42 - is 75.772 mg · mL, while that of CH3COO- is 2 0 1 -W The exchange capacity for WO42 - was 96.70 mg mL wet resin
