Poly[1,3(2-ethoxy-4-hydroxy-5-propylphenylene)propylene] copolymer as an ion exchanger

Abstract

The present paper reports the synthesis and characterization of a copolymer, The copolymer sample was synthesized by Friedel-Crafts polycondensation of 2-hydroxy-4 ethoxypropiophenone with 1,3-propane diol in the presence of polyphosphoric acid catalyst. The copolymer was characterized by elemental analysis, IR spectroscopy and viscosity study, and its number-average molecular weight (M) was determined by non-aqueous titration and found to be 2855 g mol- 1. Chelation ion-exchange properties have also been studied, employing a batch-equilibration method. It was employed to study selectivity of metal ion uptake over a wide pH range and in media of various ionic strengths. The overall rate of metal uptake follows the order UOl + > Fe³ + > Cu² + > Ni² +.
