Al-Fe柱撑膨润土的制备及其对活性艳红X-3B的吸附

Synthesis of Al-Fe pillared montmorillonite and its adsorption of dye-water

利用 Fe3+,Al3+与碱液反应制备出 OH- Fe离子、Keggin离子 ,并由此制备出不同 Fe/ ( Al+Fe)比值的 Al- Fe柱撑膨润土 ,并对其吸附有机染料——活性艳红 X- 3B的效果作了研究 (与其他几种改性膨润土进行了比较 ) .结果表明 :用 Al- Fe柱撑膨润土的层间距被明显撑大 ,有机污染物的去除率高 .

By using OH\|Fe and Keggin ions, a series of modified Al\|Fe montmorillonite are synthesized. The optimal conditions, properties and mechanisms for the modified montmorillonite series to treat the dyeing wastewater are also investigated. The results show that this modified montmorillonite series is a very cheap and highly effective absorbent to remove organic pollutant from industrial wastewater.
