Methods for the analysis of ilmenite, titanium-bearing slags, and other electric furnace slags.: M34-20/168E-PDF

“A procedure is described for the accurate and precise determination of aluminum in ilmenite, titaniferous slags, and iron ores. After fusion of the sample with sodium peroxide, triple precipitations with sodium hydroxide-peroxide solutions are performed to remove the bulk of interfering elements such as iron and titanium. The interferences remaining in the filtrate and accompanying the aluminum are removed by solvent extraction in chloroform with sodium diethyldithiocarbamate at pH 2. The aluminum in the aqueous layer is determined by means of a back-titration of an excess of 1,2-cyclohexylenedinitrilotetraacetic acid (DCYTA) with standard zinc solutions at pH 5 to 5.5 and xylenol orange as the indicator"--Summary, p. i.
