This standard specifies a method for the determination of titanium content in ferrotitanium. The ammonium ferric sulfate Titrimetric method is used. It is suitable for samples with a titanium content range of 20.00% to 80.00%. The method first dissolves the sample using sulfuric acid, nitric acid, muriatic acid and hydrofluoric acid. If there are interfering elements (such as chromium, vanadium, molybdenum and tin), hydrogen peroxide settling titanium hydroxide is used to separate interfering substances. The content of titanium is calculated by reducing titanium to trivalent by metallic aluminum and using thiocyanate as an indicator, titration is carried out using ammonium ferric sulfate standard titration solution. The standard details the requirements of the required reagents and materials to ensure the accuracy of the analytical results.
