Studies on the Analysis of Titamium Metals (2nd Report). Determination of Magnesium

Separation: On boiling a buffered acetic acid-acetate solution (at pH 3 to 6) of titanium containing minute amounts of magnesium with addition of sodium thiosulfate, titanium precipitated completely in a meta-state. Thus, magnesium could be quantitatively separated from titanium. Determination: In order to determine the quantity magnesium, the applicability of photometric method such as Oxin-Fe++, Oxin-sulfanilic NaNO2 and Mg-titan yellow was investigated by means of a spectrophotomer. These methods were found to be useful in the determination of magnesium in titanium metals with successful results.
