对海泡石去除水中砷的性能进行了实验研究 ,结果表明天然海泡石经过适当活化处理 ,对砷有很强的去除能力。在pH≥ 6.5的条件下 ,每 0 .5g经活化的海泡石可将水中 3mg/LAs降至 <0 .0 5mg/L ,该方法工艺简单 ,成本低廉 ,且不带来二次污染。
Experimental study on the performance of sepiolite to remove arsenic from water shows that natural sepiolite has a strong ability to remove arsenic after proper activation treatment. Under the condition of pH≥6.5, every 0.5 g of activated sepiolite can reduce 3mg / LAs in water to <0. 05mg / L. The method is simple in process, low in cost and does not bring secondary pollution.
