Description
Summary:A cold decomposition procedure for the spetrophotometric determination of titanium in ores and minerals is described. Samples are allowed to react with hydrofluoric acid and aqua regia at room temperature overnight. Fluoride ions in the solution are complexed with boric acid and the titanium is determined using Tiron. As fluoride ions do not have to be removed by heating, the method is rapid and avoids the use of platinum ware.
