Растворы азотной кислоты. Определение содержания плутония методом окисления церием (IV), восстановления сульфатом железа (II)-аммония и амперометрического обратного титрования бихроматом калия
Название (англ.):
Determination of plutonium in nitric acid solutions; Method by oxidation by cerium(IV), reduction by iron(II) ammonium sulfate and amperometric back-titration with potassium dichromate
Описание (англ.):
Specifies a precise and accurate analytical method which is almost specifically for plutonium. The method is suitable for direct determination of plutonium in materials ranging from pure product solutions to fast reactor fuel solutions with a uranium/plutonium ratio of up to 10 : 1, either before or after irradiation. It recommends that the aliquot of sample be weighed and that a weight titration be used inorder to obtain adequate precision, but this does not preclude using any alternative technique giving an equivalent performance.
