| 摘 要： | 研究NJ－8、AM－1、Amberlite XAD-4、JX－101 4种吸附树脂对对硝基苯乙酮和对硝基苯甲酸的静态吸附行为。结果表明：江苏南大戈德环保科技有限公司研制的NJ－8和AM－1两种吸附树脂对硝基化合物的吸附效果较好。并研究NJ－8型吸附树脂的动态吸附和脱附行为，结果显示：NJ－8型吸附树脂对对硝基苯甲酸的吸附容量为128mg/g干树脂，对对硝基苯乙酮的吸附容量为383mg/g干树脂。用8%NaOH:乙醇（体积比1：1）洗脱吸附酸的树脂，用甲醇或乙醇洗脱吸附酮的树脂，体积为5BV时，温度分别为333K和313K，脱附率均接近100％。

| Abstract: | The performances of adsorption of NJ-8, AM-1, Amberlite XAD-4, JX-101 resins for adsorbing to p-nitrobenzoin acid and p-nitroacetophenone were studied. The results of static equilibrium adsorption showed AM-1 and NJ-8 have higher adsorption capacities. The results of dynamic adsorption indicate that the adsorption capacities of NJ-8 towards p- nitrobenzoin acid and p-nitroacetophenone are 128 mg/g and 383 mg/g respectively. Nearly 100% regeneration efficiencies for both sorbents could be achieved through 5BV ethanol. |
