【摘要】：基于离子交换法提出了一种制备氨基磺酸镍的新工艺。选用聚丙烯酸系大孔弱酸性阳离子树脂,使用氢氧化钠溶液将其转型后进行离子交换,最终制得氨基磺酸镍。通过对该工艺各步骤进行实验研究得出较合理的实验操作参数:洗涤转型后的树脂时,流出液p H需小于10;离子交换时,镍离子以200 g/h的速度通过树脂层最优;洗脱镍时,氨基磺酸溶液以0.6 m/h的流速通入,多柱串联采用3个交换柱最优。实验结果表明,离子交换法制备氨基磺酸镍具有流程简单、操作方便、设备投资少等优点,同时可制备出高纯度的氨基磺酸镍。
[Abstract]:A new process for the preparation of nickel aminosulfonic acid was proposed based on ion exchange method. Polyacrylic acid macroporous weakly acidic cationic resin was used for ion exchange after transition with sodium hydroxide solution. Finally, nickel aminosulfonic acid was prepared. Through the experimental study of each step of the process, the reasonable operating parameters were obtained: when washing the resin after transformation, the effluent pH should be less than 10; In ion exchange, the nickel ion passes through the resin layer at the speed of 200 g / h. When the nickel was eluted, the amino sulfonic acid solution passed through at a flow rate of 0.6 m / h, and the three exchange columns were used in series. The experimental results showed that the preparation of nickel aminosulfonic acid by ion exchange method was simple and easy to operate. At the same time, high purity nickel aminosulfonic acid can be prepared.
