In this study, the possibility of detecting the endpoint of phenol electrolysis by UV-Vis spectroscopy was investigated by the difference absorption spectroscopy and the second derivative spectroscopy. During the electrolysis of phenol with sodium chloride as the electrolyte, the appearance of the UV-Vis absorption peak of hypochlorous acid reflected the electrolytic endpoint of phenol. The novelty of this study is that we present the possibility of discriminating the electrolytic endpoint of phenol by UV-Vis spectroscopy alone without using chemical oxygen demand (COD) or total organic carbon (TOC) measurement methods.
