摘要:
合成了胺基含量为1.35 mmol/g的乙二胺硅胶材料(EDA/SiO2),考察了溶液流速、初始浓度、装填量对其动态吸附性能的影响,研究了该体系Thomas模型参数与操作条件的关系.结果表明EDA/SiO2能有效除去水中的铜离子,随着溶液初始浓度的增大、流速的加快,使穿透时间缩短,实验发现溶液初始浓度和吸附剂装填量对Thomas模型参数的平衡吸附容量q0影响显著,流量Q对kTh的影响显著.通过离子吸附剂比强度建立了模型参数q0与C0/m呈线性关系,其方程式为:q0=0.023 4C0/m+ 0.257.该关联方程能够描述吸附操作务件与穿透曲线的关系,为该材料的应用提供一定的实验依据.
Abstract:
The ethylenediamine silica gel material (EDA/SiO2) with an amine group content of 1.35 mmol/g was synthesized, the effects of solution flow rate, initial concentration, and loading amount on its dynamic adsorption performance were investigated, and the Thomas model parameters and operating conditions of the system were studied. The results show that EDA/SiO2 can effectively remove copper ions in water, and the breakthrough time is shortened with the increase of the initial concentration of the solution and the acceleration of the flow rate. The equilibrium adsorption capacity q0 has a significant impact, and the flow Q has a significant impact on kTh. The model parameter q0 has a linear relationship with C0/m through the specific strength of the ion adsorbent, and the equation is: q0=0.023 4C0/m+ 0.257. The correlation equation can Describe the relationship between the adsorption operating conditions and the breakthrough curve, and provide a certain experimental basis for the application of this material.
