| Abstract;Here was introduced a ceramic filter with absorptive power of phosphate ions, to protect water pollution based on flowing into by phosphorous compounds. For main raw materials for phosphates absorbing agents, wollastnites of calcium silicate compounds relatively capable of inputting were used. To promote percolation of calcium, the wollastnites were mechano-chemically treated, to carry them onto ceramic filters. To avoid precipitates formation of calcium phosphate of their secondary wastes, carbonation treatment to control percolation of calcium was also carried out. |
