Abstract |
Polysaccharide-based hydrogels represent a class of materials with potential properties useful in biomedical, agricultural and environmental fields. In this work, bassorin hydrogel extracted from the Gum Tragacanth (GT) was used for the removal of a cationic dye, methylene blue (MB), from aqueous solutions. The extracted COOH-rich polysaccharide, as a plant-derived substances, was the basis for obtaining cross-linked and water-insoluble ionic hydrogel. The adsorbent possesses an important swelling property, a large surface porosity and high adsorption capacity. A series of experiments was carried out in order to study the influence of parameters such as contact time, initial MB concentration (10-100 mg\ L), adsorbent dose (1-13 g.L-1) and initial pH solution (2-10) in batch procedures at room temperature (25±2°C). The results showed that 100 min of contact time was sufficient for attaining equilibrium. The adsorption percentage increases from 55% to 84.3% when the mass of the hydrogel increases from 1g to 3g. The optimum pH for MB removal by the hydrogel was around 9. The adsorption is best described by the Langmuir model; which assumes a monolayer adsorption. Second-order model better describes the adsorption of MB on the hydrogel. We can conclude that the bassorin hydrogel has a potential, to be used as an adsorbent for wastewater treatment and purification processes to eliminate emergent contaminants |
