摘要
用2种不同助剂和4种不同含氮官能团的有机硅烷修饰剂,成功合成了8种功能化介孔硅材料,并对其进行重金属吸附试验。在重金属吸附性能研究中,采用吸附动力学研究吸附时间对吸附性能的影响,分别对一级和二级吸附速率方程进行拟合,最后确定了该介孔材料的吸附符合一级吸附速率方程。并利用吸附热力学的原理研究了吸附温度对吸附性能的影响。
Eight kinds of functionalized malodorous silica materials were synthesized successfully with two different additives and four different nitrogen-containing organic functional groups of silage modifier,and a comparison of heavy metal adsorption experiments was conducted.In the study of heavy metal adsorption properties,adsorption properties were used to study heavy metal adsorption properties,and fitted primary and secondary adsorption rate equation respectively.Finally,the adsorption of malodorous materials in line with the primary of the adsorption rate equation was determined.And the influence of adsorption performance on adsorption temperature was studied by the principle of adsorption thermodynamics.
