摘要
合成了弱酸强碱型蛇笼树脂,以腈纶纺丝溶剂为分离液,研究了温度、进样量、进样浓度、柱高等因素对蛇笼树脂分离性能的影响,进行了树脂连续分离应用试验,找出了较好的使用条件。
The snake cage resin with both carboxylic and quaternary ammonium groups was synthesized The separation ability of this resin was studied using the spinning solvent for polyacrylonitrile (sodium thiocyanate solution containing water soluble nonvolatile impurities) as separation solution Various factors such as temperature,volume of feed solution,concentration of feed solution and height of separation column were studied Then the continuous separation process was performed and the optimum separation conditions were achieved
