研究了农业废弃物香蕉皮对水溶液中活性艳蓝X-BR的静态吸附特性。探讨了吸附剂量、溶液pH、吸附时间、染料初始浓度等参数对吸附的影响,用Langmuir、Freundlich和Temkin等温式研究了吸附平衡过程。结果表明,在酸性条件下有利于香蕉皮吸附剂对活性艳蓝X-BR的吸附,吸附过程在90 min可达到平衡,香蕉皮对活性艳蓝X-BR的吸附更符合Freundlich等温式。吸附动力学研究表明,吸附过程更符合准二级动力学模型,颗粒内扩散不是吸附速率的唯一控制步骤。
The static adsorption characteristics of agricultural waste banana peel on reactive brilliant blue X-BR in aqueous solution were studied. The effects of adsorption dosage, solution pH, adsorption time and initial dye concentration on the adsorption were discussed. The adsorption equilibrium process was studied by Langmuir, Freundlich and Temkin isotherms. The results showed that the adsorption of reactive brilliant blue X-BR by the banana peel adsorbent was favorable under acidic conditions. The adsorption process reached equilibrium at 90 min. The adsorption of reactive brilliant blue X-BR by banana peel was more consistent with the Freundlich isotherm. Adsorption kinetics studies show that the adsorption process more in line with the quasi-second-order kinetic model, intraparticle diffusion is not the only control step adsorption rate.
