Tervalent neptunium in an HClO<SUB>4</SUB> solution was extracted by means of bis(2-ethylhexyl)hydrogenphosphate, HDEHP, in an octane solution. The oxidation state of neptunium in the organic phase was determined by spectrophotometry. The intense peak in the absorption spectrum of tervalent neptunium was found at 348 nm, this peak was attributed to the <I>f</I>→<I>d</I> transition. The oxidation rate of the Np(III)–HDEHP complex in an oxygen-free octane solution was about 10%/h.
