Chemically activated sugarcane bagasse for biosorption of ibuprofen from aqueous solution

ABSTRACT In this study, the ability of chemically activated sugarcane bagasse (CASB) as a biosorbent for removing ibuprofen (IBP) from aqueous solution was evaluated. Sugarcane using hexane and methanol. The effects pH, contact time, IBP concentration, temperature were evaluated in batch studies. Higher removal rates found at pH 2.0. Kinetic studies indicated that biosorption follows pseudo-second-order model. equilibrium isotherm to follow both Langmuir Freundlich models. maximum capacity CASB estimated 7.75 mg g-1 20 °C. According Dubinin-Radushkevich model, activation energy calculated be 7.07 kJ mol-1, indicating physical process mediated removal. Thermodynamic analysis suggests is exothermic nature non-spontaneous. FTIR confirmed interactions between molecules biosorbent. We concluded exhibited potential used media.
