Removal of toxic metals using a novel PHA resin-fixed bed column performance study

Abstract

The performance and efficiency of a fixed bed column loaded with a three-dimensionally crosslinked polyhydroxamic acid resin is studied with glass column. Experiments were carried out with synthetic metal solutions containing Cu(II), Sr(II), Gd(III) individually and with mixed solution containing Cu(II), Sr(II), Gd(III) and U(VI) to establish the efficiency of the fixed bed resin for a mixed solution. The “S” shaped break through curve was generated and percentage saturation of the bed was estimated. The percentage saturation at 10% breakthrough volume was found to be 68.3% for Cu(II) and Sr(II) 71.3% and 65.6% for Gd(III).
