利用建筑石膏粉和医用石膏粉进行了去除太湖水中磷的实验研究，单位重量石膏粉除磷量与溶液中磷浓度正相关，石膏粉除磷量随着pH值的增加而增加，2种石膏粉除磷规律在pH值为6和7时符合Langmuir吸附等温式，极限除磷质量比分别为0.0704 mg/g和0.0476 mg/g；在pH值为8~10的条件下除磷效果明显提高，吸附除磷量符合Freundlich吸附等温式。随着水碱度的升高石膏粉的除磷效率提高。

Architecture gypsum and medical gypsum were used to remove phosphorus from Taihu Lake water in the lab. The quantity of phosphorus removed by unit gypsum powder was positively related to the phosphorus concentration in water. The higher the pH was, the more the capacity of gypsum powder to remove phosphorus was. The capacity of the two gypsum powder to remove phosphorus fitted Langmuir adsorption equation when the pH was 6 or 7, with a maximal capacity of 0.070 4 mg/g and 0.047 6 mg/g, respectively. The capacity of gypsum powder to remove phosphorus fitted Freundlich adsorption equation when the pH was 8 to 10. The capacity of gypsum powder to remove phosphorus increased with the increasing of water alkalinity.
