以苯酚为起始剂,用先聚合后功能基化和Na离子模板的简捷方法合成了一种新型聚合物-氮杂假冠醚。研究了其对金属离子的静态吸附性能,结果表明,聚合物对Na+ 和Ca2+离子具有良好的选择吸附性能,对浓度为0.026mol/L~0.028mol/L的Na+ 和Ca2+的静态吸附容量分别达2.54mmol/g和3.06mmol/g;通过红外光谱研究了聚合物及其与Na+ 和Ca2+的配合物的结构,结果表明,在吸附聚合物中,不仅-CH2OCH2-和-CH2NCH2-参与了配位, -CH2OH和PhOCH2- 亦不同程度地参与了配位。[( )-0.1( )] | A new type of polymer, aza-pseudo-crown ether, was synthesized using phenol as a starting material and a simple method of functionalization and Na ion template after polymerization. The results show that the polymer has good selective adsorption capacity for Na + and Ca2 + ions. The static adsorption capacity of Na + and Ca2 + of 0.026mol / L ~ 0.028mol / L is up to 2.54 mmol / g and 3.06 mmol / g respectively. The structures of the polymers and their complexes with Na + and Ca2 + were studied by IR spectra. The results showed that not only -CH2OCH2- and -CH2NCH2- , -CH2OH and PhOCH2- also participated in the coordination to some extent. [() -0.1 ()] |
