What is BS 3907-4 - Determine manganese in magnesium and magnesium alloys about?
BS 3907 is a British Standard on the testing methods for the analysis of magnesium and magnesium alloys.
BS 3907-4 is the fourth part of the BS 3907 series that discusses the determination of manganese using the photometric-periodate method for the analysis of magnesium and magnesium alloys.
Who is BS 3907-4 - Determine manganese in magnesium and magnesium alloys for?
BS 3907-4 on determining manganese in magnesium and magnesium alloys applies to:
- Manufacturer of magnesium and magnesium alloys
- Manganese manufacturers
- Quality testing personnel
- Product design engineers
Why should you use BS 3907-4 - Determine manganese in magnesium and magnesium alloys?
Manganese is a trace mineral. It is vital for the human body, but people only need it in small amounts. Photometric measurement, or photometry, is a technique that can be used to measure the concentration of organic and inorganic compounds in solution by determining the absorbance of specific wavelengths of light.
BS 3907-4 provides the principle in which the sample is dissolved in sulphuric acid and oxidized with nitric acid. 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. This method is suitable for manganese content between 0.01 and 0.8 per cent. This helps you in the analysis of magnesium and magnesium alloys.
In this regard, BS 3907-4 covers apparatus and solvent required for testing as well as test sampling and procedure to determine manganese.
With BS 3907-4, you can efficiently manufacture high-quality magnesium alloys by determining the manganese using the photometric-periodate method.
