Synthesis and Adsorption Properties of a Novel Polymer Containing Cyclic Pseudo-Cryptand Ether as Functional Group for Fe3+
Abstract:
With 2-phenoxyethanol as initial material,a novel pseudo-cryptand ether polymer with crosslinking phenolic chain and nitrogen atom at the end of bridge was synthesized by a combined method of first polymerization,then cyclization and functionalization.Static adsorption properties of the polymeric cryptand ether for metallic ions were tested.The results show that the polymer has a good preferential adsorption property for Fe3+ and the adsorption capacity is 1.22 mmol/g(start concentration of Fe3+:0.053 mol/L,25℃).Within the limits,the quantity of adsorption for Fe3+ increases along with the rising of Fe3+ concentration and the increase of adsorptive time,the adsorption reaches equilibrium after three hour.The polymer has a good reprocess property and it can be fully reused.The adsorption capacities were over 1.16 mmol/g after it was used more than four times.
