Cherry stones powder and chitosan were used to prepare an adsorbent material that served to remove Biebrich Scarlet dye from aqueous matrices. Optimal working parameters were obtained by applying the Response Surface Methodology-Central Composite Design. Hence, at pH 3 and at 30 degrees C with 1 g of adsorbent, more than 90 % of the pollutant was removed from the aqueous solutions with concentrations between 10 mg/L and 50 mg/L after 4 hours of adsorption. Pseudo-2nd order kinetic model and Freundlich isotherm were established as describing with a high degree of confidence (correlation coefficients were above 0.99) the kinetic behavior and the equilibrium isotherm of the conducted process.
