摘要
以N,N,-亚甲基双丙烯酰胺(NMBA)为交联剂,在无氮气保护和不添加任何引发剂条件下,采用紫外辐照法合成魔芋粉(KF)/丙烯酰胺(AM)/马来酸酐(MA)/2-丙烯酰胺基-2-甲基丙磺酸(AMPS)共聚吸附树脂,研究了单体摩尔比、pH、交联剂用量、魔芋粉含量对树脂吸附亚甲基蓝的影响,并借助FT-IR、TG对树脂的结构、热稳定性进行了研究。实验表明:在优化条件下,n(AMPS)∶n(AM)∶n(MA)=2.5∶0.5∶0.4;w(KF)=2.5%,pH=3,w(NMBA)=0.35%,tcuring=5min时合成的树脂对亚甲基蓝的吸附量为104.14mg/g。
With N, N,-methylene bisacrylamide(NMBA)as a crosslinking agent, a copolymer adsorption resin of konjac flour(KF), acrylamide (AM), rnaleic anhydride (MA) and 2 acrylamido-2-methylpropane sulfonic acid (AMPS) was synthesized by ultraviolet irradiation without nitrogen and initiator(UV). The effect of monomer molar ratio, pH ,crosslink ing agent content, konjac flour content on the absorption of resin for methylene blue was studied, and the structure and ther- mal stability were characterized by FT-IR and TG, respectively. The results showed that the absorbing power was 104. 14mg/g for methylene blue in the optimum conditions of nAMes " nAM " nMA =2. 5 : 0. 5 . 0.4;w(KF) =2.5%,pH=3, w (NMBA) = 0.35%, tcuring = 5min.
