Application of Composite Hydrogel of Clinoptilolite crosslinked wheat Straw-g-Potassium Acrylate to Dye Sorption

A composite hybrid hydrogel was prepared by incorporating the zeolite (natural surfactant modified clinoptilolite) into a graft poly (potassium acrylate) on wheat straw powder hydrogel by the in situ polymerization method using N,N'-methylene bisacrylamide as organic cross-linker. The dye sorption/adsorption properties of this hybrid hydrogel were investigated. The adsorptions of MB dye (as a cationic dye) by the hydrogel increases as the loading of the clinoptilolite particles and dye concentration increases. The hybrid hydrogel and hydrogel without any inorganic particle were investigated by FTIR. SEM and XRD were used to characterize the crystalline and microstructure of hybrid and organic hydrogels.
