摘　　要：一步合成了新型钇掺杂TiO2柱撑膨润土作为吸附剂,吸附甲基橙、刚果红、活性艳蓝和罗丹明B四种模拟印染有机废水。对吸附的动力学模型和等温吸附模型进行了拟合,其动力学行为基本符合与Bangham和Langmuir方程,吸附的性能基本符合Freundlich和Langmuir吸附等温方程。并探讨pH和染料结构对吸附结果造成的影响。A new type of yttrium-doped TiO2 pillared bentonite was synthesized in one step as an adsorbent to adsorb four kinds of simulated printing and dyeing organic wastewater:Methyl Orange,Congo Red,Reactive Brilliant Blue,and Rhodamine B.The kinetic model of adsorption and the isothermal adsorption model were fitted,and its kinetic behavior basically accorded with the Bangham and Langmuir equations,and the adsorption performance basically conformed to the Freundlich and Langmuir adsorption isotherm equations.The effect of pH and dye molecular structure on the adsorption results was discussed.
