摘要
研究了用粘土和天然絮凝剂MR去除水中氟离子的机理 ,探讨了吸附时间、溶液温度及 pH对吸附的影响。结果证明 ,吸附过程属一级反应 ,在不同温度下吸附平衡遵循Lang muir等温式。同时也计算了热力学参数。
The mechanism of adsorbing fluorion in water by clay and natural flocculant MR was studied.The effects of adsorption time,adsorption temperature and water pH on adsorption were explored.The results show that the adsorption is the reaction of first order;the adsorption equilibrium in different temperature follows Langmuir isotherm.Thermodynamic parameters were also calculated.
