Description

Behavior of Np(V) in strong nitric acid solutions with different strength (1,0 ÷ 3,0) mol∙l-1 and KPW (1 ÷ 5)∙10-3 mol∙l-1, containing potassium phosphotungstate, K10P2W17O61 (KPW) is examined by spectrophotometric method . It is established that Np (V) final conversion products under studied experimental conditions are Np (IV) and Np (VI), and the process is going in accordance with a first-order rate law in regard to neptunium(V) concentration.
