Development of HPLC method for the analysis of chlorophenols in samples from anaerobic reactors for wastewater treatment

This article describes an HPLC method for routine samples analysis of labor atory scale anaerobic immobilized sludge reactors used for degradation of p entachlorophenol (PCP) in synthetic wastewater. The method was developed to quantify pentachlorophenol and six chlorophenol isomers produced during th e degradation of pentachlorophenol by anaerobic bacteria. The validated met hod was used for anaerobic reactor samples and was able to quantify the chl orophenol intermediates produced.
