Abstract
In this research, the graft copolymerization of 2-hydroxy propyl methacrylate-acrylic acid
mixture onto poly (ethylene terephthalate) fibers, in the presence of benzoyl peroxide as an initiator was
accomplished. The Modified fibers were used as a new adsorbent for removal of cetyl pyridinum bromide
from aqueous solution. The adsorption data were best fitted by Freundlich isotherm and pseudo first
order kinetic models, as well. Thermodynamic parameters like enthalpy, entropy and Gibbs free energy
have been determined. The results were emphasized that, the adsorption process was unspontaneous
and feasible.
