以N,N-二甲基烯丙基胺,5-氯甲基水杨醛及邻氨基苯酚为原料合成5-[氯化(N,N-二甲基-N-烯丙基铵基)甲基]水杨醛缩邻氨基苯酚(DMAA-QAs-HAE),之后以甲基丙烯酸甲酯为共聚单体,二甲基丙烯酸乙二醇酯为交联剂,偶氮二异丁腈为引发剂,采用悬浮聚合法,制得携带季铵阳离子的铜(Ⅱ)离子印迹聚合物[Cu(Ⅱ)-IIPs]。实验结果表明:在pH=4,铜(Ⅱ)离子初始浓度为800mg/L,25℃,吸附15min,Cu(Ⅱ)-IIPs对铜(Ⅱ)离子的最大吸附量可达52.78mg/g,对干扰离子Fe~(3+)、Pb~(2+)、Cd~(2+)和Ni~(2+)都有良好的选择吸附性能。
Synthesis of 5- [N, N-dimethyl-N-allylammonium chloride] using N, N-dimethylallylamine, 5-chloromethyl salicylaldehyde and o- Methyl] salicylaldehyde o-o-aminophenol (DMAA-QAs-HAE), followed by methyl methacrylate as comonomer, ethylene glycol dimethacrylate as a crosslinking agent, azobisisobutyronitrile as The Cu (Ⅱ) ion imprinted polymers [Cu (Ⅱ) -IIPs] carrying quaternary ammonium cations were prepared by suspension polymerization. The experimental results show that the maximum adsorption capacity of Cu (Ⅱ) -IIPs to copper (Ⅱ) reaches 52.78mg / g at pH = 4, initial concentration of Cu (Ⅱ) is 800mg / L, It has good selective adsorption properties for the interference ions Fe ~ (3 +), Pb ~ (2 +), Cd ~ (2+) and Ni ~ (2+)
