Optimization of Sono-Electrocoagulation Process for the Removal of Dye Using Central Composite Design
Journal Title: Mehran University Research Journal of Engineering and Technology - Year 2019, Vol 38, Issue 2
Abstract
Sono-electrocaogulation process was successfully applied for the removal of RR120 (Reactive Red 120) in the presence of activated carbon. For this purpose, the process variables were optimized using CCD (Central Composite Design). The operational parameters of the technology were the amount of activated charcoal (0.2-2.0g), amount of NaCl electrolyte (1-10g), sonication time (30-120 min) and RR120 dye concentration (40-120 mg/L), respectively. Consequently, the 100% dye removal was determined at the optimal conditions for the process obtained by CCD. In addition, the sonication time, amount of adsorbent and dye concentrations were found the significant process factors. Furthermore, the effects of other parameters like the electric current, current efficiency, amount of NaCl, temperature and formation of coagulants were also studied in the dye removal process, separately. The FTIR (Fourier Transfer Infrared) spectrums were monitored to identify the classes of functional groups present in the dye molecule before and after the treatment. Therefore, the sono-electrocaogulation process was proved an effective technique for purifying simulated wastewater containing RR120 dye.
