中文摘要:

      本文研究了在恒速搅拌下，不同温度光卤石在芒湖溶液中溶解及转化机理，用溶解过程离子实验值拟合得到动力学方程并求得了溶解反应的表观活化能，为生产硫酸钾提供了一定的基础。

英文摘要:

      The dissolution and transformation of carnallite at constant stirring velocity and surface area of carnallite at different temperature in Na2SO4 solution has been studied.The kinetice equations of dissolution and crystallize have been fitted by experiment data of ions concentration of dissolution process. And the active energy of dissolution have been obtanined. We can provide the base of preduction.
