Reference: Patent, 27.01.1999, Sosnovyi Bor patent holder: State enterprise Leningrad Nuclear Power Plant named after V.I. Lenin

Keywords: liquid waste, treatment, potassium cobalt ferrocyanide

Abstract: The present invention relates to the field of disposal of radioactive waste from nuclear plants, in particular to radioactive waste liquid. The method consists of heating the oil, of alkaline potassium permanganate, and ferrocyanide collector to 80oC, in volume ratio of the two being 0.5:5:0 (collector:oil), with formation of coagulant and subsequent separation of radioactive sludge. As ferrocyanide collector, 1. potassium cobalt ferrocyanide or 2. mixture of potassium nickel ferrocyanide and potassium cobalt ferrocyanide can be used.
