摘要
为有效去除水溶液中的刚果红染料,采用阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)对沸石进行改性。刚果红在改性沸石上的吸附量远远大于未改性沸石的吸附量。考察了吸附时间、溶液pH值、离子强度等因素对改性沸石吸附效果的影响。通过对吸附等温线进行分析,沸石对刚果红的吸附很好的符合Langmuir吸附模型。
Hexadecyl trimethyl ammonium Bromide （CTAB） modified zeolite was prepared and used as an adsorbent for Congo red in aqueous solution. Adsorption capacities of modified zeolite for Congo red is much larger than that of non - modified zeolite. The adsorption properties were studied. Finally, adsorption model was applied to the adsorption, and the datas obeyed Langmuir adsorption isotherm.
