摘要：

A novel dibenzopolyether resin possessing dicarboxylic acid side arm functionality (EDPAR) was synthesized by condensation polymerization of ethylenedi(oxy-o-phenoxyacetic acid) with formaldehyde in formic acid. The excellent sorption for Pb(II) over Cu(III) obtained with EDPAR was not observed with commercially available iminodiacetic acid resin (CR-10). For EDPAR, the percent sorption of Pb(II) exceeded 90% at pH 2.5, while Cu(II) sorption was less than 30% at this pH.
