Characterization of blending hydrogel biochar derived from sugarcane bagasse and fly ash as an adsorbent

Biomass are a good choice to be used as an adsorbent due to their availabiltyintheenvironemnt and reducing the waste in surroundings indirectly. Large volumeofindustrial by-products, for instance palm kernel shell, sugarcane bagasse, sawdust, rice husk and others are produced. In this study, biochar fromSaccharumofficinarum (L), or sugarcane bagasse (SB) was obtained using slowpyrolysis. Theraw sample with different ratio of biochar and flyash (FA) was blended with hydrogel. The hydrogel was produced by mixing the biochar with a monomer, that isacrylamide (AAm), a cross-linker, that is methylenebisacrylamide (MBA), andwiththe presence of an initiator, that is ammonium persulfate (APS). The properties andcharacteristics of the blended hydrogel biochar have been made through different instrumental methods like field emission scanning electron microscope (FESEM) toobtain the pore structure and distribution, Brunauer-Emmett-Teller (BET) surfacearea analysis and proximate analysis using Thermogravimetric Analysis (TGA). Theblended hydrogel biochar of ratio 50:50 (SB:FA) is found to be a better adsorbent with having larger surface area of 3.7297 m2 /g and its fixed carbon percentage of 24.7655%.
