Application of LPME/GC-ECD for determination of PCP in water [PDF]
Science in China Series B: Chemistry, 2003 Liquid-phase microextraction (LPME) followed by gas chromatography (GC) coupled with an electron capture detector (ECD) was applied for the analysis of pentachlorophenol (PCP) in aqueous samples. After alkalization with Na2CO3 solution, PCP was acetylated with acetic anhydride.
