强酸阳树脂和强碱阴树脂的混杂,国内外至今没有很好的测试方法。本文根据离子交换树脂与有色无机离子的交换反应使树脂显色的原理和pH指示剂使树脂染色的原理,为判断强酸阳树脂和强碱阴树脂混杂程度提供了简易方便、准确迅速的测试手段。
Strong acid cation resin and strong mixed anion resin, at home and abroad so far there is no good test method. According to the principle that the resin is colored by the exchange reaction of ion exchange resin and colored inorganic ion and the principle that the pH indicator makes the resin dyed, this paper provides a simple, convenient and accurate test method for judging the degree of mixture of strong acid cation resin and strong anion anion resin .
