Abstract:

The adsorption behavior of Au(Ⅲ) ions on the quaternary ammonium-based ultrahigh molecular weight polyethylene fiber (UHMWPE) fibrous adsorbent (UHMWPE-g-P(GMA-co-MA)-TETA-GTA) prepared by pre-irradiation grafting technique was investigated, while influences of initial pH value of the solution, Au(Ⅲ) ion concentrations and temperature were also concerned. The results showed that the adsorption equilibrium of UHMWPE-g-P (GMA-co-MA)-TETA-GTA fiber for Au(Ⅲ) adsorption could be reached within 180 min and the adsorption capacity reached maximum(355 mg/g) at pH=3. Adsorption kinetic pattern is in good agreement with the pseudo-second-order model, and the Langmuir isotherm model fits the adsorption equilibrium data well. This adsorption reaction is an exothermic reaction entropy reduction.
