Abstract
A new nitro derivative of β-naphthol was synthesized. Its structure was studied by 1HMR and IR spectrometry. A possibility of its use for immobilization on fibrous substrates and application as a specific analytical reagent for the determination of metal ions, in particular, cobalt(II) ions, was shown. The absorbance maximum of the reagent is at 490 nm and of the complex with cobalt ions, 690 nm. A procedure was proposed for the determination of cobalt(II) in wastewater.
