This study investigated the influence of experimental factors on the electrochemical cyanide destruction efficiency in a flow-through reactor using response surface methodology. Central composite experimental design was used to obtain the four main operating factors, such as current density, initial cyanide concentration, chloride concentration, and electrolysis time, on the response surface of cyanide destruction efficiency. Analysis of variance (ANOVA) showed a high coefficient of determination value (R2) and insignificant lack of fit for the quadratic response surface model. The Pareto analysis gave the percentage effect of each factor on the response.
Key words: Response surface methodology, cyanide destruction, electrolysis.
