Description

Influence of acid-base properties of media on formation of gaseous radiolysis products during gamma-irradiation (60Co) of sodium nitrate (nitrate+acetate) aqueous solutions by doses up to 350 kGy at 60 deg C in the presence of feldspar particles was studied using gas chromatographic method. It was ascertained that feldspar actually does not produce any effect on gas formation during irradiation of alkaline and acid solutions, however, in neutral solution the radiation-chemical yields increase approximately twofold. The observed effect is explained by occurrence of heterogeneous radiolysis of adsorbed components of neutral solution and water molecules

Abstract (Russian)

С использованием газохроматографического метода изучено влияние кислотно-основных свойств среды на образование газообразных продуктов радиолиза при гамма-облучении (60Co) водных растворов нитрата (нитрата+ацетата) натрия дозами до 350 кГр при 60 град С в присутствии частиц полевого шпата. Установлено, что полевой шпат практически не оказывает влияния на газообразование при облучении щелочного и кислого растворов, однако в нейтральном растворе радиационно-химические выходы возрастают примерно в два раза. Наблюдаемый эффект объясняется протеканием гетерогенного радиолиза адсорбированных компонентов нейтрального раствора и молекулы воды
