A Battue on Anionic Dye (congo red) Removal from Aqueous Solution of Dye by Acryl amide Grafted Polyethylene

Abstract

Polymer modification has drawn much attention in the recent time among which modification by grafting is one of the most selective method. Radiation induced graft polymerization was employed for synthesis of acryl amide grafted polyethylene (AAm-g-PE) adsorbent. Different irradiation doses, monomer concentration and distilled water as a solvent were used to optimize grafting yield. The percentage of Grafting was optimized found to be 383% which was obtained for 6% monomer concentration at 12 kGy radiation dose without initiator in distilled water. The prepared grafted polyethylene was characterized by Fourier Transform Infrared Spectrometer (FTIR). The prepared grafted materials were used to be removed anionic dye (congo red) from aqueous solution of dye. The effectiveness of the adsorbent for removing dye from aqueous solution was evaluated by batch technique. The influences of different experimental parameters on removal process such as contact time and dye concentration were evaluated. Results showed that initial dye concentration of 30 ppm at pH 6.10 yields 65.4% dye removal efficiency by AAm-g-PE film.
