SORPTION OF LEAD ION FROM AQUEOUS SOLUTION BY CARBOXYLIC ACID GROUPS CONTAINING ADSORBENT POLYMER

ABSTRACT Novel method to synthesize of p-(2,2,3,3-tetracarboxylic acid cyclopropyl)phenyl acrylate(P-TCP) was disclosed. In this study,3-(4-hydroxyphenyl)cyclopropane-1,1,2,2-tetracarboxylicacid was synthesized by the new method and reacted with acryloyl chloride to preparation of P-TCP monomer. The...

In this study,3-(4-hydroxyphenyl)cyclopropane-1,1,2,2-tetracarboxylicacid was synthesized by the new method and reacted with acryloyl chloride to preparation of P-TCP monomer. Then the resulting monomer was polymerized by free-radical polymerization initiated with benzoyl peroxide in ethyl acetate a solvent to obtain a poly-(2,2,3,3- tetra carboxylic acid cyclopropyl)phenyl acrylate (PTCP)with multicarboxylic acid cyclopropane functionalities in the pendant group as a new polymer and applied to remove Pb(II) from aqueous solution.
