| Abstract: | A new polysilicate boron aluminum(PSBA) was prepared by using sodium silicate,(aluminum) (sulfate) and boricic acid as raw materials.The factors effecting the properties of PSBA,such as the molar ratio of SiO_2 to B, SiO_2 to B and Al were studied,and the optimum conditions were determined by the (experiments.)PSBA made under the optimum conditions was used in the treatment of indigo wastewater. The results showed that the removement rate of COD_(Cr) and decolorness property were superior to other sorts of (inorganic) polymer flocculants in the marketplace. It has advantages of wide range pH and eminent stability. |
