摘要

这项工作的重点是研究用硫酸活化的天然粘土和柱状粘土处理含腐植酸的水溶液。20 分钟后似乎达到了平衡。在低 pH 值介质（pH = 4）中，使用粒径为 Ø <2 μm 的粘土，可获得最大的消除率。与未加工的粘土相比，带柱粘土可固定 124% 以上的腐殖酸。柱状粘土的吸附能力最大，这表明铝可能是腐殖酸的首选吸附位点。

Assessment of the crystallochemical properties of the natural and modified clays in the organic matter removal during the water treatment process

The study of natural clays, activated with sulfuric acid and pillared clays for treating aqueous solutions containing humic acids was the focus of this work. It appears that the equilibrium is reached after 20 min. A max elimination yield is obtained with pillared clay in a low pH medium (pH = 4) using clays of size Ø <2 μm. Pillared clay fixes more than 124% of humic acids compared to raw clay. The maximum adsorption capacities of clays are obtained with pillared clay, which is an indication that Al is probably the preferred adsorption site of humic acids.
