| 摘 要： | 以新疆夏子街钠基膨润土为原料,制备了无机柱撑膨润土和无机—有机柱撑膨润土,考察了溶剂及配比等对柱撑膨润土的影响。无机柱撑膨润土的合成条件为OH-]/Al3+]=2.2,Al3+/土=15mmol/g。膨润土应用于城市污水的吸附研究结果表明:膨润土原矿对废水中COD去除率为38.5%,无机柱撑膨润土在最优吸附条件下对废水中COD去除率达到91.85%,无机—有机柱撑膨润土在最优吸附条件下对废水中COD去除率达到97.12%。

| Abstract: | In this testwork,the inorganic pillar bearing bentonite and inorganic-organic pillar bearing bentonites were prepared with Xinjiang Xiazijie sodium bentonite.The synthetic condition of inorganic pillar bearing bentonite is as follows:/=2.2,Al3+/bentonite=15mmol/g.These pillar bearing bentonites have been used in testwork of sewage water treatment.It was shown that the COD removal rate of sodium bentonite is 38.5%,the COD removal rate of inorganic pillar bearing bentonite is 91.85% under the optimum condition,and the COD removal rate of inorganic-organic pillar bearing bentonite is 97.12% under the optimum condition. |
