| 摘 要： | 利用巯基乙酸方法对苹果皮、柚子皮进行改性处理。通过在不同温度、吸附剂质量和六价铬溶液浓度的条件下,对改性后的苹果皮和柚子皮吸附六价铬溶液的吸附性能进行比较。结果表明,温度、吸附质浓度对吸附剂的吸附效果影响明显。二者的吸附过程都符合二级动力学方程。

| Abstract: | Apple, grapefruit peel was modified by acetic acid method. The adsorption effects of the modified apple and grapefruit peel by absorbing hexavalent chromium solution, at different temperatures, the sorbent mass and concentration conditions are compared. The results show that, temperature and the sorbent concentration can obviously influent the adsorption. Finally, preliminary pharmacokinetic analysis is used in the modification of apple peel and grapefruit peel. The two adsorption processes are in line with the two order kinetics equation. |
