Abstract
A method of preparing a polyferricsilicate water purifier is disclosed. Raw materials include sintered pyrite slag, diatomite, sulfuric acid and sodium silicate. The method achieves effective utilization of the sintered pyrite slag, turns waste into things of value, and overcomes the problem that the sintered pyrite slag is difficult to treat. The water purifier is simple in preparation, wide in pH value using range, and capable of effectively treating a plurality of pollutants in water and significantly reducing contents of harmful compounds such as heavy metals in water. The water purifier is prepared mainly from the sintered pyrite slag and the diatomite so that the water purifier is low in cost and free of generation of secondary pollution. The water purifier is high in adsorptive power and has characteristics of good water purification effects and a high water purification speed.
