TPEN (N,N,N′,N′-tetrakis(2-pyridylmethyl)ethylenediamine) derivatives of different skeleton of the ethylene moiety are designed and synthesized. The obtained product is subjected to radical copolymerization with N-isopropylacrylamide (NIPA) to afford the polymer gel. Temperature-dependent extraction performance of TPEN derivatives and the corresponding polymer gels is compared at different temperatures and pH values.
设计并合成了乙烯部分具有不同骨架的TPEN(N,N,N′,N′-四(2-吡啶甲基)乙二胺)衍生物。将所得产物与N-异丙基丙烯酰胺(NIPA)进行自由基共聚反应,得到聚合物凝胶。在不同温度和pH值下,比较了TPEN衍生物和相应聚合物凝胶的温度依赖性萃取性能。
