标准范围

该方法包括分解有机物,然后用羟基氯化铵还原三价铁,在缓冲介质中形成稳定的铁(II)/1,10菲咯啉络合物,并在508nm波长下光度测量红色络合物。

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.
