| 摘 要： | 通过静态试验方法研究了ZrO2 纳米颗粒液相吸附联苯胺的性能 ,结果表明 ,虽然联苯胺均可与ZrO2 纳米颗粒表面羟基及水分子形成氢键 ,但它与ZrO2 纳米颗粒表面羟基之间形成的氢键稍强 ,吸附去除效果较好 ,该吸附体系很好吻合Freundlich和deBoer Zwikker吸附等温式 ,热分析显示联苯胺与ZrO2 纳米颗粒表面之间的吸附成键作用较弱。

| Abstract: | The adsorption effect of benzidine on ZrO 2 nanometer powders in the aqueous solution is studied.The results show that hydrogen bond can be formed by benzidine and hydroxyl group or hydrone on the surface of ZrO 2 powders,but the one by benzidine and hydroxyl group is slightly stronger than the one by benzidine and hydrone,the removal efficiency is about 61%.The adsorption system can be well in accord with isothermal equations of Freundlich and equation de Boer-Ziwkker.The thermogravimetric and differential thermal analyses demonstrated that there has a weak adsorption between benzidine and nanometer powder. |
