Investigation of color pollution removal in synthetic wastewaters by response surface method modeling

DahaIn the conducted master's thesis, the treatment of synthetically prepared wastewater using the electro-oxidation process was investigated. The synthetic wastewater was prepared using cationic dyes of the acrylic type, including Doracryl Yellow, Doracryl Red, and Doracryl Blue, which are used in the textile industry. The electrooxidation system was carried out using Ti/IrO2/RuO2 as the anode material and uncoated titanium as the cathode material. In the study, experimental conditions were determined through modeling using the Design Expert program. Thirty experiments were planned for each dye in the modelling. The results of the experiments carried out in line with the conditions created by the model were poured into three-dimensional graphics in the Design Expert program and the response surface method was applied. In the experiments, current density, pH, supporting electrolyte concentration (SEC) and initial dye concentration (C0) parameters were examined. In order to ensure conductivity, 5 mM, 10 mM and 15 mM NaCl were preferred as supporting electrolyte type (SET). A modeling study was carried out using the data obtained as a result of 15-minute experiments. As a result of the experiments, dye removal efficiency and energy consumption values were calculated. Color removal efficiency: While it increases with the increase in current density and supporting electrolyte concentration, it decreases with the increase in pH and initial dye concentration. A similar trend is observed in energy consumption values. sonra doldurulacaktır.
