Окислительная очистка жидких радиоактивных отходов от органических соединений и радионуклидов перманганатом калия

Л.И. Руденко, О.В. Джужа, В.Е. Хан

Abstract
The oxidizing purification of liquid radioactive waste (LRW) from organic substances and radionuclides with the use of a water solution of potassium permanganat is investigated. At a mass ratio of organic substances and a 5% solution of potassium permanganat of 1.5 : 1 in a strongly sour environment, the dichromate oxidizability decreases from 2360 to 100 mg O₂/dm³, the concentration of uranium from 42 to 1.3 mg/dm³ and the activity of ⁹⁰Sr from 2.2 · 10⁷ to 3.5 · 10⁴ Bq/dm³ decrease. The basic opportunity of the oxidizing purification of LRW with the use of a water solution of potassium permanganat for the preliminary preparation of LRW at a stage prior to the evaporating devices of the Chernobyl NPP is shown.
