研究了以双氮杂假冠醚环为主体功能基的酚醛型聚合物对金属离子的吸附性能。结果表明,聚合物对K+,Hg2+,Na+,Cd2+,Pb2+ 和Cu2+离子具有良好的吸附性能,其吸附容量分别达1.79mmol/g-r,1.38mmol/g-r,0.89mmol/g-r,0.68mmol/g-r,0.63mmol/g-r和0.57mmol/g-r,对K+和Hg2+离子具有良好的吸附选择性。通过FTIR光谱法对吸附机理作了初步探讨。
The adsorption properties of metal ions on phenolic polymers with diazacrown ether ring as the main functional group were studied. The results showed that the polymer has good adsorption capacity for K +, Hg2 +, Na +, Cd2 +, Pb2 + and Cu2 + ions and the adsorption capacity is 1.79mmol / gr, 0.38mmol / gr, 0.68mmol / mmol / gr and 0.57 mmol / gr, which have good adsorption selectivity to K + and Hg2 + ions. Adsorption mechanism was studied by FTIR spectroscopy.
