| 摘 要： | 金属离子改性的凹凸棒石和膨润土对水中活性艳红染料Ｋ－２ＢＰ的吸附脱色作用符合Ｆｒｅｕｎｄｌｉｃｈ吸附等温式并呈现一级反应动力学的特征，吸附的最佳ＰＨ范围分别为〈５和〈６，其中以改性凹凸棒石的吸附性能较好，光照检验表明，改性膨润土还具有一定的光化学催化降解作用。

| Abstract: | Adsorption decolourization of activated dye K - ZBP from water with metallic cations modified at tapulgite and bentonite could be expressed with Freundlich model and characterized by the first-order kinetics, and the optimum pH ranges were less than 5 and 6 respectively, while the modified attapulgite presented better adsorption performance. The tests also showed that the modified bentonite could photocatalytically degrade the dye to some extent. |
