摘要:
以氢氧化镁改性沸石为吸附剂,研究了其对水溶液中甲基橙的吸附性能,用准一级和准二级动力学、Elovich、粒子扩散及Fick动力学等方程对不同浓度、吸附时间的吸附曲线进行分析,研究了其吸附动力学机理.结果表明:改性沸石吸附甲基橙是复杂的非均相扩散的化学吸附过程,吸附过程由膜扩散和粒子内扩散联合控制,并通过Fick方程计算了吸附过程的有效扩散系数.
Abstract:
The adsorption property of magnesium hydroxide modified zeolite for Methyl Orange ( MO) in aque-ous solution was studied. The adsorption curves were analyzed at different MO concentration and adsorptiontime using pseudo-second order kinetic equation,Elovich equation. The kinetic adsorption mechanism wasstudied.The result showed that the adsorption of MO on Mg(OH),/ zeolite is a complex heterogeneous dffu-sion chemical adsorption process. The intraparticlar diffusion equation indicated that the adsorption rate of MOwas controlled by the combination of film diffusion and intraparticle diffusion.
