Abstract: A new method for the determination of aliphatic chloro acids by atomic absorption spectrometry after the extraction of their ion-associates involving dipyridylocopper(II) and phenanthrolinocopper(II) complexes was elaborated. Nitrobenzene was used as a suitable extraction solvent. The method enabled to determine units of a milligram of trichloroacetic acid and 2,2'-dichloropropionic acid in pesticide preparations.
