Adsorption of Remazol Brilliant Violet-5R from Aqueous Solution Using Sugarcane Bagasse as Biosorbent: Kinetic and Thermodynamic Studies

Sugarcane bagasse is an inexpensive and eco-friendly natural biosorbent for the removal of various organic pollutants. The adsorption Remazol Brilliant Violet-5R (RBV-5R) dye on sugarcane (SCB) was studied. Biosorbent characterized using EDX FTIR. effect experimental parameters, such as pH, dosage, initial concentration, contact time, with shaking without shaking, temperature, optimized. At pH 6, maximum biosorption 92.22% achieved 0.15 g SCB. equilibrium attained within 30–40 min RBV-5R. concentration 10 µg/mL determined optimum RBV-5R at 30 °C. Langmuir Freundlich isotherms were applied, it found that follows isotherms. Kinetic studies also carried out proposed method followed pseudo-second-order kinetic model (R2 = 0.98). From desorption study, in increasing order obtained ethanol, methanol, 0.2 M sodium hydroxide (NaOH). study applied to actual textile waste effluent pave way practical usage this technology a larger scale results effective.
