BS 3907 is a British Standard on the testing methods for the analysis of magnesium and magnesium alloys.
BS 3907-5 is the fifth part of the BS 3907 series that discusses the determination of manganese using the photometric-periodate method with low contents for the analysis of magnesium and magnesium alloys.
BS 3907-5 on determining manganese in magnesium and magnesium alloys applies to:
Manganese is a trace mineral. It is vital for the human body, but people only need it in small amounts. BS 3907-5 provides you with the principle in which the sample is dissolved in sulphuric acid and oxidized with ammonium persulphate. The manganous ions are oxidized to permanganic acid with potassium periodate in the presence of phosphoric acid. The optical density is measured at about 525 nm. The method is suitable for manganese contents of less than 0.01 per cent. This method helps you in the analysis of magnesium and magnesium alloys.
In this regard, BS 3907-5 covers apparatus and solvent required for testing as well as test sampling and procedure to determine manganese.
With BS 3907-5, you can efficiently manufacture high-quality magnesium alloys by determining the manganese using the photometric-periodate method with low contents.
