Abstract

A novel method was developed for the indirect determination of chlorophenols by AAS after extraction of their ionic associates involving the dipyridylocopper(II) (CuDP) or phenanthrolinocopper(II) (CuPH) complex into nitrobenzene, <i>o</i>-dichlorbenzene or methyl isobutyl ketone. Nitrobenzene appeared to be particularly suitable for the extraction of the CuDP associate, methyl isobutyl ketone, for the extraction of the CuPH associate. Thee method is applicable to chlorophenol concentrations of 10<sup>-6</sup> to 10<sup>-7</sup> mol l<sup>-1</sup>. Using CuDP after a single complete extraction into 10 ml of nitrobenzene, the lowest determinable concentration giving rise to absorbance <i>A</i> = 0.010 is 0.3 mg of pentachlorophenol in a litre; using CuPH after a single extraction into 10 ml of methyl isobutyl ketone, it is 0.2 mg of chlorophenol in a litre.
