摘要：

An extraction method for separation of iron(III), copper(II), and cobart(II) is described; subsequently, these elements are analyzed by atomic-absorption spectrophotometry in an extract - acetone mixture (1 : 1). The potential use of N-(1-phenyl-2,3-dimethylpyrazolone-5)-C-(1-phenyl-3-methylpyrazolone-5)-phenylazomethine as a new extractant for Fe(III), Ni(II), Mn(II), Co(III), Cr(III), Cu(II), and Zn(II) is considered. Conditions for complexation of iron(III), copper(II), and cobalt(II) are specified and an extractive atomic-absorption method for analysis of these elements in copper alloys is proposed.
