| 摘 要： | 以膨润土和四氯化钛为原料,采用水热法制备TiO2/膨润土柱撑复合材料,探讨了复合材料对甲基橙的吸附性能。结果显示,TiO2/膨润土柱撑复合材料在平衡浓度0~6 mg/L范围内,吸附等温曲线符Freundlich吸附等温方程,吸附动力学曲线遵Langmuir方程,吸附速率常数k-Na-Ti-Mt=0.340 3,吸附方式是分配和表面吸附的协同效应,且以分配作用为主,可作为很好的吸附污染有机物的材料。 |

| Abstract: | TiO2/bentonite pillared composite were prepared by hydrothermal method with bentonite and TiCl4 as raw materials.Methyl orange was particularly conducted to study the absorption.The isothermal absorption of TiO2/bentonite pillared composite followed the Freundlich equation for equilibrium concentration between 0 and 6 mg/L.Absorption kinetics were conformed with Langmuir equation.The absorptive rate constant was k-Na-Ti-Mt=0.340 3.Synergism of distribution and surface absorption in absoption process was studied,and the distribution showed the leading effect.It was anticipated that they could be used as adsorbent for polluting organic substance. |
