Paper Title:
Comparison of Dye Adsorption Behaviors of Sodium Polyacrylates Freely Dissolved in Water and Grafted onto Poly(Ethylene Terephthalate) Fiber
  Abstract

Dyes containing wastewater lead to severe environmental pollution. Polyacrylates both dissolved in water and bonded to polyester fabrics were used to remove dye molecules from simulated wastewater. The Fourier transform infrared spectra, scanning electron microscopy and UV spectrophotometry were applied to characterize the grafting and the adsorption behavior of polyacrylates. The adsorption behaviors were described by the Lagergren’s pseudo second kinetic equation with physical interaction mechanism. The adsorption rate and equilibrium value were almost independent of adsorption temperature. The chemical bonding substantially suppressed the polymer chain mobility and thus weakened the removal efficiency.
