Crosslinked copolymer(AA/beta-CD-AA/ABE) containing beta-cyclodextrin was synthesized by microwave heating with acylation, allyl-biphenyl-ether(ABE), crylic acid(AA) as monomer and N, N-methylenebisacrylamide (MBA) as cross-linking agent, and characterized by means of FTIR. The adsorption of Pb2+ and Zn2+ on the synthesized copolymer and the factors (adsorption time, pH and temperature) which affect the adsorption capacity were investigated by atomic absorption spectrometry (AAS) as the detection means. The results show that the optimum experimental conditions of adsorption: 35 degrees C, 2 h and pH 2-3, adsorbance Q for Pb2+ reached maximum 29.5 mg x g(-1); 30 degrees C, 3 h and pH 3-4, adsorbance Q for Zn2+ reached maximum 43.7 mg x g(-1); the adsorption equilibriums for Pb2+ and Zn2+ fit the Freundlich on the whole. |
