离子交换树脂最适再生条件探索

THE MOST SUITABLE REGENERATION CONDITIONS OF ION EXCHANGE RESIN

离子交换法制纯水是厂矿、科研单位常用的纯水制备方法．在制出一定量合格水后，树脂吸附饱和，用酸碱对树脂进行再生，使树脂恢复交换能力．试验表明，再生剂用量、再生液浓度、再生液流出速度等对设备周期采水量及水质均有显著的影响。

The ion exchange is a most popular method in making pure water in all kinds of laboratories. Having produced fixed quantity satisfactory water, resin adsorption reached the saturation and resin was regenerated with acid or alkali in other to make it recovery exchange ability. The declares that regenerant dose, regenerant concentration, the velocity of flow of the regenerant and others have notable effect on the equipment's periodic water output and water quality.
