Abstract
This study aims to investigate the performance of polyaluminum chloride (PAC) as a coagulant to remove Acid blue 292 (AB292), which is used widely in textile industry in Iran. The effect of pH, coagulant dosage, kaolinite (as a natural coagulant aid), and initial dye concentration were examined in the coagulation process with PAC. Results showed that the optimum pH range to remove AB292 was 6-8. In such conditions, the dye removal using 40 mg/L of PAC was more than 83%. This dosage (40 mg/L) was considered as the optimum dosage of PAC to remove AB292. Addition of kaolinite as a coagulant aid increased the efficiency of the process. With the aid of 40 mg/L kaolinite, dye removal efficiency increased by 30% when the coagulant dosage was 30 mg/L. As the initial dye concentration increased, the dye removal efficiency decreased, so that the efficiency for dye concentrations of 25 and 250 mg/L was 95% and 21%, respectively.
