中文摘要:

      研究了不同温度下，不同温度的ＮａＣｌ溶液对钾光卤石溶解转化的影响，得出ＮａＣｌ的浓度对溶解转化的影响不大，且温度对光卤石的溶解转化的影响不是简单线性关系的结论。计算了该体系光卤石的溶解动力学方程和氯化钾结晶动力学方程。

英文摘要:

      In this paper, We have studied the effects of temperature and concentration of NaClsolution on dissolution on carnallite. The results shown that the effect of NaCl concentrationon dissolution of carnallite is little, but the effect of temperture is complicated. The kineticequations for the dissolution of carnallite and for the crystallization of KCl in NaCl aqueoussolution have been given.
