Synthesis and Characterization of Terpolymer Adsorbents Using Photopolymerization: Investigation of Heavy Metal Adsorption Capacity

In this study, poly(allylphenol-co-methylmethacrylate-co-vinyl imidazole) (PAMV) terpolymer adsorbents were synthesized using the photopolymerization method with 1-vinyl imidazole, methyl methacrylate, and 2-allylphenol monomers. Structural and surface analyzes of PAMV polymers obtained using different mole ratios 1H-Nuclear Magnetic Resonance, Fourier-Transform Infrared Spectroscopy, X-Ray Photoelectron Spectroscopy, Scanning Electron Microscopy-Energy Dispersive X-Ray and thermal characterization were performed using Thermogravimetry methods. Inductively Coupled Plasma Mass Spectrometry was used for adsorption studies. Optimization studies were carried out at different pH values. According to the results obtained, the pH range in which adsorbents operate at maximum efficiency is between 6-10. Although many different metals have been studied, the holding capacity of the obtained polymeric adsorbent on cadmium, chromium and mercury metal ions is quite remarkable.
