【摘要】 在研究了３种大孔型阳离子交换树脂脱除食品稀糖液中Ｃａ２＋、Ｍｇ２＋效能的基础上，对稀糖液中Ｃａ２＋、Ｍｇ２＋除去效果最好，交换能力最大的Ａｍｂｅｒｌｉｔｅ２５２树脂采用化学转化法进行磁化处理。比较磁化前后的阳离子交换树脂对食品稀糖液中Ｃａ２＋、Ｍｇ２＋的除去效果，结果表明，磁化过程并不影响树脂的交换容量更多还原

【Abstract】 The elimination of Ca2+ and Mg2+ from diluted sugar liquor by three kinds of larger pores cation exchange resins was systematically studied. The Amberlite 252 resin was most effective for the elimination of Ca2+ and Mg2+ in diluted sugar liquor among the three larger pores. It was proceeded by chemical transformation and became magnetic anion exchange resin. Then the elimination of Ca2+ and Mg2+ was compared Amberlite 252 resin with magnetic cation exchange resin. The results indicated that the exchange capacity wasn’t seriously influenced by magnetization process.更多还原
