| 摘 要： | 改性凹凸棒石是一种价格低廉的新型吸附剂,通过改性后,使得它具有比表面积大、化学稳定性好、吸附能力强等特征,对水中多种污染物具有很好的去除力。经对阳离子染料废水和重金属铬的处理,其染料废水的脱色率和COD去除率分别达到87.5%～99.8%和45.4%～72.3%,铬的去除率可达到82%。

| Abstract: | Modified attapulgite is a new low cost adsorbent. which gives attapulgites virtues of high surface area,inert chemical property and excellent adsorptive property by modification, its application to the water treatment is invested.Ion cation dyestuff waster and heavy metal chromium. Decolour rate and exorcize rate of dyestuff waste water could reach 87.5%~99.8% and 45.4%~72.3%. The chromium exorcize rate could reach 82%. |
