The principle of the method specified is to decompose a test portion by alkaline fusion with sodium carbonate and subsequent acidification with hydrochloric acid in the presence of boric acid to complex fluoride, selective reduction to the blue molybdosilicic acid complex, spectrometric measurement of the absorbance of the coloured complex at a wavelength corresponding to the absorption maximum…

The method specified is based on alkaline fusion of a test portion with a mixture of sodium carbonate and boric acid, dissolution of the melt in excess hydrochloric acid, reduction of the iron(III) with hydroxylammonium chloride, formation of the iron(II)-1,10-phenanthroline complex in a buffered medium (pH between 3 and 5), spectrometric measurement of the absorbance of the coloured complex at a…
