Selective removal method of monovalent anions in feed liquid

The invention discloses a selective removal method of monovalent anions in feed liquid. The monovalent anions in the feed liquid are effectively removed in a removal experimental device by utilizing the permselectivity of anion exchange membranes to the monovalent anions and combining with the adsorption effect of a capacitive deionization unit. According to the selective removal method, differentmonovalent anion selective exchange membranes are utilized to combine with the capacitive deionization technology, certain operation voltage, feeding flow rate and operation time are adopted to achieve selective removal of the monovalent anions aiming at the feed liquid with certain components, pH and concentration, the technological process of the method is simple and easy to operate, the cost is low, the efficiency is high, and the method is green and environmentally friendly. 本发明公开了种料液中单价阴离子选择性脱除方法。它利用阴离子交换膜对单价离子的选择性透过，结合电容去离子单元的吸附作用，在脱除实验装置中对料液中的单价阴离子的有效去除。本发明通过使用不同的单价阴离子选择性交换膜结合电容去离子技术，对于定组分、pH、浓度的料液，采用定的操作电压、进料
