N2 - UV-Vis spectroscopy for monitoring of aromatic compound degradation during electrooxidation is completely restricted by -OCl/ClO2 produced in the system. The -OCl/ClO2 absorbance masks the aromatic compounds absorbance in the UV region (260-350 nm). This study presents a method for the qualitative monitoring of degradation of aromatic compounds which has an absorbance at a UV region (260-350 nm) of the spectrum by simply removing -OCl/ClO2 from the solution using sodium meta-bisulfite (SMBS). The strategy was evaluated by monitoring of in situ hypochlorite mediated electrooxidation of real textile effluent. The degradation of aromatic compounds measured by UV-Vis spectrum analysis was supported by fluorescence spectroscopy analysis and HPLC analysis. This method can be a handy tool to monitor the degradation of any organic compounds which has an absorbance in the 250-300 nm region during an advanced electrooxidation process in the presence of chloride.
