Abstract
In the current scenario, removal of toxic dyes from dye contaminated water has become a major challenging task to world researchers because disposal of untreated dye effluents into water bodies have adverse effect towards the ecosystem. Keeping this in mind, the present study aims to utilize the sugarcane bagasse biochar (SBB) and its composite with iron oxide nanoparticle (Fe3O4/SBB) to estimate for the decontamination their batch scale potential of Congo red (CR) dye from aqueous solution. The synthesized adsorbent were characterized by FT-IR, XRD, FE-SEM, TEM, VSM, EDX, and BET surface area analysis. The effect of adsorbent dosages (50-130 mg), initial CR concentration (10-100 mg/L), pH (3-11), and contact time (5-240 min) were evaluated CR removal on Fe3O4/SBB at room temperature. The adsorption data well fit with Langmuir isotherm (R2 = 0.99) and pseudo second order kinetics (R2 = 0.99). The maximum adsorption capacity was found to be 74.07 mg/g.
