摘　　要：本文描述了用黄铁矿和还原铁粉或其代用品为原料制备含砷废水净化剂——硫化亚铁的新方法,获得了制备的最佳条件,探讨了其在含砷废废水处理中的应用条件和影响因素.结果表明,该净化剂的生产及其处理含砷废水的工艺简单,经济高效.具有良好的开发应用前景.This paper discribed a new method to prepare a cleaning agent FeS, by using pyrite and reduced iron powder or substitutes for removal of arsenic from wastewater. The optimums of preparation were obtained. The conditions and factors that have influences on the agent to remove arsenic from wastewater were discussed. The results showed that the production and application of the agent are simple, effective and economical. Therefore, there is a good spectacle of opening up and application.
