| Abstract: | The performances and the utilization situation of bentonite, often called as "universal clay", are introduced briefly. With acid activation treatment, the activated-clay can be obtained from the bentonite. An excellent activated-clay can be prepared by activating calcium bentonite with vitriolic solution of 1.5-2.5 mol/L under the conditions of appropriate temperature and liquid/solid ratio. Experimental results indicate that its decolorizing efficiency and activity is 97% and 200, respectively. |
