A thin-layer chromatographic method with densitometric detection was
established for quantification of p-chlorophenol in waste water. Degradation
efficiency of p-chlorophenol was monitored after each treatment of the
wastewater samples. Degradation of p-chlorophenol was performed with advanced
oxidation processes (AOPs), using UV, H2O2/UV, O3/H2O2/UV, O3 and O3/UV.
Developed TLC procedure has been found to be simple, rapid and precise. The
method was characterized by high sensitivity (limit of detection was 11 ng
per band and limit of quantification 35 ng per band), linear range (from 75
to 500 ng per band, r = 0.9965), and high precision, accuracy (mean
percentage recovery 98.6%), and specificity. Additionally, the efficiency of
degradation was monitored using HPLC giving comparable results with RP TLC
measurements.
