Synthesis of mesoporou s SBA-۱۵ nanopar ticles using stem sweep ash silica for adsorptio n kinetics of the cationic dye, Azure B, from aqueous solut ion

In thi s study, the application of Synthe sized mesop orous SBA-۱۵ nanopa rticles from stem sweep ash (SSA) silica for adsorption kinetics of the cationic dy e from aque ous solution were inverstigated. silica was extracted from SSA with approximat ely ۸۰% purity. The p resent study used stem sweep, whic h is an agric ultural wast e, as silica source for m esoporous SBA-۱۵ nanoparticles. The synthe sized SBA -۱۵ nanopar ticles are rod-like sha pes with average diameter of ۸۲ n m and length in the ra nge of ۵۰-۲۵۰ nm. Finally in this work, adso rption kineti cs of a cati onic dye, Azure B, from aqueous solution were evaluate d with resp ect to initial dye concentration, temp erature, pH, mixing rat e and sorben t dosage .
