【摘要】 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( )] |更多还原

【Abstract】 Phenol as starting material, a novel polymetic pseudo azacrown ether were synthesized by short cut methods of first polymerization, then functionalization and Na+ as template guided, Its static adsorption properties for metal ions were studied. The results showed that the polymer has good selective adsorption properties for Na+ and Ca2+, the capacities of absorption were 2.54mmol/g and 3.06mmol/g respectively at the concentration of 0.026mol/L ~0.027mol/L. The structures of the polymer and complexes with Na+, Ca2+ were studied by FTIR spectroscopy. The results showed that not only could -CH2-O-CH2- and --2|2CHNCH chelate metal ion, but also -CH2OH and PhoCH2- did to a certain extent in the above mentioned complexes in the above mentioned complexes.更多还原
