A study has been made of the extraction of copper (II) by 1 M solutions of capric acid in toluene and n-heptane, and also in n-heptane in the presence of pyridine, benzylamine, or 1,10-phenanthroline. The compositions of the copper compounds with capric acid and amines that are extracted were established by photometric and polarographic methods. An extractionatomic absorption method is proposed for determining copper in river water, with a detection limit of 0.3 mu g/liter.
