| Abstract | ||||
| In this work , grafting polymerization using gamma radiation from C0-60 source at room temperature (27°C) was employed to produce a novel adsorbent using Acrylamide (AAm), Acrylic acid (AAc) on carboxymethyl cellulose (CMC) for water treatment . The preparation conditions such as effect of Acrylamide (AAm) and Acrylic acid (AAc) concentration and radiation dose on grafting percent were investigated to achieve the optimum grafting percent. The structure, thermal stability and surface morphology were characterized by Fourier transform infrared spectroscopy (FT-IR) & differential scanning calorimetry (DSC) and scanning electron microscopy (SEM), respectively. The results show that for the same radiation dose, the grafting percent is increased with increasing the concentration of acrylamide and acrylic acid (1:1) in solution till 30 % where the best grafting percent obtained. The grafting percent increases with increasing irradiation doses. The grafted Carboxymethyl cellulose (CMC-g-AAm/AAc) was examined and optimized for its application as adsorbent for wastewater treatment. | ||||
