长期以来，人们迫切需要一种直接分光光度法来测定微量氯化物。这种方法现在被提出，基于高氯酸铁（III）的使用。铁（III）的氯络合物在340 µ附近显示出强烈的吸收带，并有助于定量测量。所提出的方法是准确的，相对不受干扰。大量的硫酸盐往往会干扰。然而，该方法可以在存在其他卤化物和几乎所有其他常见离子的情况下使用。
There has long been a great need for a direct spectro-photometric method for the determination of small amounts of chloride. Such a procedure is now pro-posed, based on the use of iron (III) perchlorate. Chloro complexes of iron (III) exhibit an intense absorption band in the vicinity of 340 µ and lend themselves to quantitative measurement. The proposed procedure is accurate and relatively free from interferences. Large amounts of sulfate tend to interfere. However, the method can be used in the presence of the other halides and practically all other common ions.
