Determination of neptunium and plutonium in their mutual presence by potential-controlled coulometry

Review of works by soviet and foreign authors where theoretical bases and practical application of potential-controlled coulometry (PCC) method are presented, is given. By PCC method it is proposed to determine neptunium and plutonium under their combined presence in various objects. Main conditions fo conducting analysis are presented. PCC method is the most accurate one when determining neptunium. It is applicable in the presence of large uranium quantities and can be automized
