Abstract
A study was made to establish proper conditions for the selective determination of Fe(II) by the 1,10-phenanthroline method in the presence of large amounts of Fe(III). It was shown that fe(III) is effectively masked by fluoride. The pH of the solution to be masked should be below 2.5 in order to prevent acceleration by the fluoride of aerial oxidation of Fe(II).
摘要
开展了一项研究，以确定在大量Fe(III)存在的情况下，用1,10 - 菲啰啉法选择性测定Fe(II)的合适条件。结果表明，Fe(III)能被氟化物有效掩蔽。为防止氟化物加速Fe(II)的空气氧化，待掩蔽溶液的pH应低于2.5。
