**What is BS 1728-6 - Determination of iron by volumetric titanous chloride method about?**

BS 1728 is a British Standard on the testing methods for the analysis of aluminium and aluminium alloys.

BS 1728-6 is the sixth part of the BS 1728 series that discusses the determination of iron using the volumetric titanous chloride method for the analysis of aluminium and aluminium alloys. Aluminium alloys are widely used in engineering structures and components requiring lightweight or corrosion resistance.

**Who is BS 1728-6 - Determination of iron by volumetric titanous chloride method for?**

BS 1728-6 on the determination of iron by volumetric titanous chloride method applies to:

Manufacturer of aluminium products and alloys
Iron manufacturers
Product design engineers
Quality testing personnel

**Why should you use BS 1728-6 - Determination of iron by volumetric titanous chloride method?**

Titanous chloride is used to make titanium metal and other titanium-containing compounds, such as titanium dioxide, which is used as a white pigment in paints and other products and to produce other chemicals.

BS 1728-6 provides you with the principle of iron in which the alloys are dissolved in mixed acids and fumed with sulphuric acid. The siliceous residue is filtered off and any traces of retained iron are recovered by subsequent treatment of the ignited residue. Copper is precipitated by hydrogen sulphide and the copper sulphide is filtered off. The hydrogen sulphide is removed from the filtrate by boiling and the iron is oxidized and then determined by titration with titanous chloride solution.

BS 1728-6 gives you a method that is suitable for iron contents between 0.1 and 5.0 per cent. This method helps you with the analysis of aluminium and aluminium alloys. BS 1728-6 exemplifies the iron using the volumetric- titanous chloride method for the analysis of aluminium and aluminium alloys.
