摘要

We report the copolymerization synthesis of novel poly(allylisothiocyanate-co-hydroxyethylmethacrylate-co-vinylimidazole) (PAHV) adsorbents for potential applications in the heavy metal removals. In the present study, the copolymerization reaction was introduced by photopolymerization using benzophenone as the photoinitiator. The chemical structure in the PAHV adsorbents was monitored and evaluated by Fourier transform infrared spectroscopy, H-1-nuclear magnetic resonance, andX-ray photoelectron spectroscopy measurements. Surface analysis and molecular weight distribution of PAHV adsorbents were performed by scanning electron microscopy and gel permeation chromatography analysis, respectively. The adsorption method, which is one of the most effective techniques, was used for the elimination of heavy metal ions from aqueous solutions in this study. In order to understand the adsorption capacity and removal efficiency of heavy metal ions by PAHV, the effects of pH value and monomer ratio in the adsorbents were investigated. Inductively coupled plasma mass spectrometry device was used for these analyses. The optimum pH values for adsorption capacity and removal efficiency of heavy metal ions have been 6-8. The removal efficiency of heavy metal ions by the various PAHV adsorbents decreased in the order: Cd2+ > Pb2+ > Co3+ > Cr3+ > Ni2+ > Cu2+.
