The study examined the performance of the proxy electrocoagulation method in removing Cefixime from water on a laboratory scale. Results showed a removal rate of up to 92.25% under optimal conditions, with the statistical adequacy of the model confirmed. Peroxidation electrocoagulation was found to be an effective method for removing CFX, but more research on its economic viability is needed.
The objective of this study was to examine the performance of the proxy electrocoagulation method in removing Cefixime (CFX) from water. This study was performed on a laboratory scale on synthetic samples of the antibiotic CFX in a batch reactor. In this study, the effect of five parameters was investigated, such as initial CFX concentration, Hydrogen peroxide concentration, pH, current intensity and reaction time. The results show that under optimal conditions, Proxy Electrocoagulation Process can remove CFX up to 92.25% with a desirability of 1.0. Central composite design (CCD) proposed a quadratic model for this process. Hydrogen peroxide concentration, solution pH, current density and reaction time, was investigated using a CCD. The adequacy of the model was confirmed using statistical tests such as; F-values of 17.66, p-values of 0.0001 and lack of fit of 0.552 for the model, respectively, R-2 = 0.819, R-adj(2) = 0.77, R-pred(2) = 0.66, AP = 19.23. Peroxidation electrocoagulation can be an effective method in removing the antibiotic CFX from water. Of course, more research should be done economically compared to other methods. [GRAPHICS] .
