适用范围

The standard describes a method for the determination of the uranium content in UO₂(NO₃) solutions. After transfer into a nitric acid solution, uranium can also be determined in UF₆, UO₂F₂ and powders or tablets of U₃O₈, UO₂, UO₂/Gd₂O₃, (U,Pu)O₂,(Th,U)O₂, and UAL_x. The potentiometric titration is only little influenced by other ions.#,,#
