摘　　要：实验采用离子交换树脂法吸附对硝基苯酚和邻硝基苯酚,树脂选型确定了强碱性阴离子交换树脂KIP209对两种硝基苯酚吸附容量最大。用所选的树脂KIP209对两种硝基苯酚进行吸附实验研究,实验结果表明:溶液初始p H为6.0时最有利于吸附,两种硝基苯酚吸附率均随树脂用量的增加而增大;树脂KIP209对两种硝基苯酚的吸附都符合Langmuir方程;吸附动力学可以很好地用拟二级方程表示;用5%的Na OH对吸附后的饱和树脂进行脱附,效果较好。The adsorption of p- and o- nitrophenol in aqueous solution with ion exchange resins were studied in the resin selection experiment and KIP209 strong base anion exchange resin showed the maximum capacity. The adsorption properties of the selected KIP209 resin for p- and o- nitrophenol were studied by static experiments and the results showed that the suitable p H is 6.0, and the removal percentage of p- and o- nitrophenol increases with the consumption of resin. The adsorption behavior of KIP209 of pand o- nitrophenol, which was the favourable adsorption, conform well to the Langmuir isotherm equation respectively while the adsorption process both correspond with pseudo-second-order kinetic model and the desorption efficiency of resin to o- and p- nitrophenol with 5% sodium hydroxide could be better.
