A new chelating resin, poly(4-ethoxy-2,4-dioxobutyl 2-methylacrylate), functionalized with beta-dicarbonyl units derived from a newly synthesized monomer was prepared and characterized with molecular spectroscopic methods. The synthesized polymer was used for the separation and preconcentration of Mn(II), Co(II), Ni(II), Zn(II), and Pb(II) ions before their determination by flame atomic absorption spectrometry. The effects of different parameters, such as pH of sample solution, sample and eluent flow rates, volumes of sample and eluent, concentration and type of eluent, and matrix ions on quantitative recovery of the analytes were evaluated for optimal experimental conditions. The adsorption capacities of the chelating resin for cobalt(II) and nickel(II) were found to be 24.2 and 19.8 mg g(-1), respectively. Validation studies for the proposed method were performed using three certified reference materials, and the results obtained were agreed with those of the certified values. The proposed method was successfully applied to the analysis of water samples. (C) 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 127:2414-2421, 2013
