Abstract: Factorial and central composite design experiments were performed to maximize the percentage removal of hydrolyzed reactive red 194 (HRR) from a simulated textile effluent by using Brazilian pine fruit wastes. Solution pH, initial dye concentration, contact time, and adsorbent mass levels were systematically varied for both untreated and acid-treated wastes. Biosorbent dosage of 9.0 g L-1, pH of 2.0, and at least 7-8 h contact time resulted in 98% dye removal for the acid-treated wastes and 88% for the untreated wastes. Adsorption isotherms were determined for both materials at the optimized conditions, and the equilibrium data was better fitted to the Sips isotherm model.
