摘要：
The removal of textile dyes (CI acid blue 40 and CI basic blue 41) from aqueous solutions, by adsorption on activated carbon prepared from rice hulls (ACRH), have been investigated depending on pH, activated carbon dosage, contact time and initial concentration. The optimum values of pH, contact time and activated carbon dosage at 75 mg/L initial concentration and 100 mL volume of the dyes solutions have been determined as 2-9, 20 min and 0.25 for CI basic blue 41 and 2-6, 40 min. and 0.50 g for CI acid blue 40, respectively. Freundlich and Langmuir equations were applied for the adsorption of both dyes and their adsorption followed both isotherms. Adsorption capacity has been found as 130.87 and 53.55 mg/g for CI basic blue 41 and CI acid blue 40 from Langmuir isotherms, respectively.
