of pyrrhotite being 12 g/L. Key words: pyrrhotite; As(III); water treatment; mechanically activated 砷(As)是一种有毒非金属元素,在自然界中主要以硫化物的形式存在,在还原环境下,微量的砷可转入地下水中,经过迁移和富集可使地下水中的砷含量增加,长期饮用将会严重影响人的身心健康[1].在有色冶金行业的生产中,往往...除率影响不大. 图12 磨矿时间对机械活化的磁黄铁矿去除溶液中As(III)的效率的影响 Fig. 12 Effect of grinding time on As(III) removal efficiency in mechanically activated pyrrhotite solution 由实验结果可知:在未经搅拌磨磨矿之前,磁黄铁矿表面与空气中的氧作用,发生氧化反应,生成了S的......
