Provided are methods of purifying quaternary onium salts having the steps of (a) providing an quaternary onium salt solution having a first ionic impurity concentration; (b) providing an ion exchange material charged with electrochemically stable anions; and (c) contacting the salt solution with the ion exchange material to produce an quaternary onium salt solution having a second halide concentration is less than the first ionic impurity concentration.
所提供的季鎓盐提纯方法具有以下步骤:(a) 提供具有第一离子杂质浓度的季鎓盐溶液;(b) 提供充有电化学稳定阴离子的离子交换材料;(c) 将盐溶液与离子交换材料接触,生成第二卤化物浓度低于第一离子杂质浓度的季鎓盐溶液。
