Synthesis and characterization of zeolite-g-polyacrylamide (Zeolite-g-PAAM) by using simultaneous irradiation technique

Abstract

Abstract In this study, we synthesized the adsorbent based zeolite as an adsorbent for toxic metal removal. The modified zeolite adsorbent has been successfully synthesized using polymerization radiation technique by gamma rays. The monomer of acrylamide was applied to be grafted onto zeolite. The irradiation doses used in this study were 10–75 kGy and we obtained the optimum dose for synthesizing the zeolite-g-polyacrylamide by using the simultaneous irradiation technique was 25 kGy, with 99.88% and 48.01% for the gel fraction and degree of grafting, respectively. The zeolite-g-polyacrylamide were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Differential Thermal Analysis (DTA) and Scanning Electron Microscope (SEM).
