| 摘 要： | 以氨基葡萄糖和聚苯乙烯为原料合成新的螯合树脂,检测了螯合树脂的氯含量和红外光谱;然后利用氨基葡萄糖螯合树脂与硼的螯合性质,通过实验研究其对硼的吸附能力,并研究了温度、时间等影响螯合树脂吸附的因素。根据热力学有关原理,计算出树脂吸附硼的热力学数据,从而得出树脂对硼的吸附效果。结果表明:合成的螯合树脂对硼有一定的吸附效果;较高温度有利于吸附,为吸热反应;ΔG小于0,吸附过程可以自发的进行。

| Abstract: | A new chelating resin was synthesized using glucosamine and polystyrene as material, the infrared spectra and contents of chlorine were detected. The adsorption for boron was studied by using the chelating properties of glu- cosamine toward boron. The temperature and time of chelating resin for boron adsorption were studied. It was also meas- ured the adsorption isotherms of boron adsorption at different temperature, and the adsorption mechanism and capacity was discussed according to the relationship of thermodynamic function. The results showed that the resin exhibited high adsorp- tion for boron, higher temperatures was favorable to adsorption, than 0, and the adsorption process could be spontaneous. this reaction was an exothermic reaction, AG was less |
