摘要：

The extraction of ionic associates of nickel and cobalt(II) with nitrosooaphthols and basic dyes has been studied. The organic complexes of nickel and cobalt(II) with nitrosonaphthols are shown to be extracted from alkaline mixtures by low-polarity solvents in the form of ionic associates with basic dyes. The composition and basic spectrophotometric characteristics of extracted compounds and optimal conditions of their preparation have been established. The method for determining Ni-II and Co-II in waters has been worked out.
