ANALYSIS OF PHENOLS AND OXIDATION INTERMEDIATES IN COKING WASTEWATER BY HPLC

ABSTRACT The simultaneous determination of phenol, cresol, polyphenol and their degradation products was important to evaluate the biodegradability of real wastewater. In the present study a reversed phase high performance liquid chromatography method was developed and validated for simultaneous det...

In the present study a reversed phase high performance liquid chromatography method was developed and validated for simultaneous determination of phenol (PhOH), o-cresol (o-C), p-cresol (p-C), hydroquinone (HQ), benzoquinone (BQ), catechol (CTL), p-hydroxybenzoic acid (p-HBZO) and p-hydroxybenzaldehyde (p-BZAL).

The degradation products including low-toxicity p-BZAL and p-HBZO were detected in the treated wastewater. The pH of wastewater was important to avoid generation of highly toxic compounds.
