功能化偶氮杯[4]芳烃羧基衍生物的合成及其对铀的吸附实验研究
Experimental Study on Synthesis of Azocalix [4] Arene Derivative with Carboxylation Functional Group and Its Adsorption of Uranium
摘要
Abstract
A novel functionalization material,5,11,17,23-4(4-hydroxyazobenzene)-25,26,27,28-calix [4]arene(p-TTPTA),was synthesized.This material was based on the calix [4] arene and decorated with p-aminobenzoic acid on the edege of the calix [4] arene.The p-TTPTA was characterized by FT-IR,1H NMR,SEM and EDS.The effects of adsorption time,pH,dosage of p-TTPTA,initial uranium concentration and temperature on the adsorption of uranium by p-TTPTA were investigated.The results show that the p-TTPTA has stable conformation,rough surface,wide specific surface area and chemical compound with uranium.The optimal condition for the adsorption of uranium by p-TTPTA is pH＝5,the initial uranium concentration of 20 mg/L,p-TTPT A dosage of 20 mg,time of 8 h and temperament of 30 ℃.According to above analysis,p-TTPT A can adsorb better uranium.关键词
