چکیده
Background and purpose: Reactive Blue ۱۹(RB۱۹) dye is one of the major dangers to human health and environment. Hence, the removal of these compounds from polluted water has been considered. This study was an attempt to investigate the removal of RB۱۹ dye from aqueous solution in the presence of modified pistachio shell. Materials and Methods: In this experimental study, the treatability of water polluted with RB۱۹dye was investigated by using sonochemical oxidation in a reactor. The sample with the desired concentrations of dye (۱۰-۸۰ mg/L) at pH ۲-۱۱ was prepared, then the required concentrations of MPS (۰.۱– ۱.۲ g/L) was flowed into the reactor intermittently. Results: The results of the current study showed that ۴۰.۲۶% of the dye was removed in the presence of MPS after ۲۰ min at pH ۲, MPS dose ۰.۷ g/L, and concentration of ۲۰ mg/L. Conclusion: The findings showed that the combined process of ultrasonic and adsorption in the presence of MPS at optimal conditions of operation can be used as an acceptable option in the removal of dye from waters.کلیدواژه ها
