本文阐述了在大量阳离子和阴离子存在下,用铁(Ⅰ)-磷酸-亚铁嗪(Ferrozine)法测定铀(Ⅵ),对于25毫升中含8—75微克铀的浓度范围,测定的相对精密度为3—1%。
This paper describes the determination of uranium (Ⅵ) by the Ferrozine method in the presence of a large amount of cations and anions. For a concentration range of 8-75 ug of uranium in 25 ml, the relative precision The degree is 3-1%.
