Abstract:

Polysaccharide-based hydrogels offer a great overlook for environmental applications and help in the elimination of various noxious pollutants from the water system. Novel superadsorbent hydrogel having appreciable swelling properties and adsorption capacity towards Methylene blue (MB) was synthesized by suspension polymerization technique. The hydrogel grafting conditions were optimized by studying the effects of different parameters (temperature, stirring rate, initiator concentration, monomer to polysaccharide ratio). For ascertaining the maximum adsorption capacity, various influential parameters such as contact time, adsorbent dose, dye concentration, and temperature were systematically studied. Maximum adsorption capacity as calculated from the Langmuir isotherm was 3300 mg/g for MB dye. Kinetics studies revealed that the adsorption process follows pseudo-second order reaction kinetics. Overall, the present study reveals that the synthesized superadsorbent hydrogel can be used as an efficient adsorbent for the removal of dyes from an aqueous solution.
