摘　　要：本文以亚氨基二乙酸螯合树脂为骨架,将三价铁负载到树脂上,构建了基于铁氟配位的新型除氟吸附剂,并探究了铁负载螯合树脂对废水中氟的吸附性能。结果表明:在pH是控制该载铁亚氨基螯合树脂除氟效果的关键条件,pH=4时具有最大的吸附量;吸附平衡时间为150min,其最大吸附量为175.4mg/g。铁负载IDA树脂对氟的吸附过程是吸热反应,温度的升高有利于吸附。In this paper,a new fluoride removal adsorbent based on iron-fluorine coordination was prepared by loading Fe3+onto the resin.The adsorption performance of Fe-loaded resin for fluoride in wastewater was investigated.The results showed that pH was the key condition for fluoride removal by Fe-loaded IDA resin,and the maximum adsorption capacity was obtained at pH=4.The adsorption equilibrium time was 150 min,and the maximum adsorption capacity was175.4 mg/g.The adsorption process is an endothermic reaction.The increase of temperature is beneficial to the adsorption process.
