标准摘要
[中文适用范围]： 该方法包括分解有机物，然后用氯化羟铵还原三价铁，在缓冲介质中形成稳定的铁(II)/1,10菲咯啉络合物，并在100℃下对红色络合物进行光度测量。 波长为508 nm。 [外文原描述]： The method consists in decomposing the organic matter, followed by reduction of trivalent iron by hydroxyammonium chloride, forming, in a buffered medium, of the stable iron(II)/1,10 phenanthroline complex, and photometric measuring of the red-coloured complex at a wavelength of 508 nm.
英文名称Fruits, vegetables and derived products — Determination of iron content — 1,10- Phenanthroline photometric method
