Description

Properties of aluminium nitrides prepared by diverse methods to be used as nitrogen-containing material for preparation of 14C by means of irradiation with thermal neutrons in a nuclear reactor are considered. Feasibility of complete separation of carbon from irradiated aluminium nitride using potassium bichromate as oxidant is shown. Efficiency of carbon-14 dioxide separation from a gaseous mixture with nitrogen and its oxides evolved during oxidation of irradiated nitrides using absorbers with potassium permanganate and sodium hydroxide was studied

Abstract (Russian)

Рассмотрены свойства нитридов алюминия, полученных разными методами, применительно к использованию в качестве азотсодержащего материала для получения 14С облучением тепловыми нейтронами в ядерном реакторе. Показана возможность полного выделения углерода из облученного нитрида алюминия с использованием в качестве окислителя бихромата калия. Исследована эффективность выделения диоксида углерода-14 из газовой смеси с азотом и его оксидами, выделяющейся при окислении облученного нитрида, с использованием поглотителей с растворами перманганата калия и гидроксида натрия
