| Abstract: | A kind of new adsorbent which was made of the mixture of γ -Al2O3, attapulgite and starch at a certain ratio, was studied. The characteristics of adsorption and diffusion of the adsorbent agent were studied at the condition of different material ratios and roasting temperatures. Furthermore, the influences of pH value, concentration of methylene blue on adsorbing methylene blue by the compound adsorbent were studied. According to the experiments, the adsorbent had a good adsorptivity and low loss rate. At the condition of alkalinity, it can adsorb methylene blue better. |
