| Abstract: | Preparation method of Attapulgite clags-flyash Parficle adsorbent is studied. The recorery and modification of the same are carried out. By employing specific surface area determination and X ray energy specfrum methods etc,the above said adsorbent manufactured is symptomatized. The results indicate that the optimum condition of preparing particle adsorbent is Attapulgite clays:flyash=100:40(mass ratio) and the specific surface area is 80.06m 2/g. This adsorbent can be modified by 1mol/L phospboric acid and the specific surface area of the same is 155.60m 2/g after modificafion. |
