摘要

用多晶材料旋转圆盘研究了硬石膏和石膏在25℃下的溶解动力学，并用钙选择电极进行了动力学研究。石膏的溶解速率受输运控制，硬石膏的溶解速率介于化学和输运控制之间。

Dissolution rates of polycrystalline samples of gypsum and orthorhombic forms of calcium sulphate by a rotating disc method

The dissolution into water of anhydrite and gypsum was studied at 25°C using a rotating disc of polycrystalline material, and the kinetics were followed with a calcium selective electrode. The dissolution rate of gypsum was transport controlled while that of anhydrite was intermediate between chemical and transport control.
