%X In this work, produced water (PW) from offshore exploration was electrochemically oxidised utilising ruthenium oxide (Ti/RuO2) anode in a lab-scale electrolytic batch cell. Electrolysis time, starting pH, and current density (CD) have all been examined for their effects. The sum of initial concentrations of 16 priority PAHs in PW was 160 g/dm3. At optimum conditions, including CD of 10 mA/cm2, pH 6, and electrolysis time of 4 h, maximum PAHs removal was 98 . The CD, starting pH, and electrolysis duration were all optimised using the RSM-based Box-Behnken (BBD) experimental design. The trials findings demonstrated that the quadratic model, based on BBD, was appropriate for the data (P value > 0.0001), and the suggested model was supported by a high R-squared value. The polynomial regression model was chosen as the best fit model for optimization in the current investigation based on ANOVA. Low probability values and the model's F-values suggested that the elimination of PAHs is important. According to the findings, electrocatalytic oxidation with a Ti/RuO2 anode is a potentially effective method for removing PAHs from aqueous solutions. © 2023 The Author(s)
