摘　　要：本文研究了硫酸铝水解生成的凝絮状氢氧化铝溶胶在最佳酸碱度条件下对氟离子Ｆ－的吸附特征，得到了Ｆ／Ａｌ（质量）比小于１时的吸附等温方程式的具体形式及Ｆ／Ａｌ（质量）比大于１时的线性方程，同时还从理论上对它们进行了解释。The treatise researches adsorbing characteristic of aluminum hydroxide floc from the hydrolysate of aluminum sulfate for the fluorous ions F- under optimum condition of acid acidity and basicity. The specific form of the adsorption isothermic equation have been obtained on condition that F/Al (mass)proportion is smaller than one.and we have obtained a linear equation only if F/Al (mass) proportion more than one.simultaneously this paper carries out explanation on them in the theory.
