ASTM D4606 – Standard Test Method for Determination of Arsenic and Selenium in Coal by the Hydride Generation/Atomic Absorption Method
Description:
Significance and Use
4.1 This test method permits measurement of the total mass fraction of arsenic and selenium in coal for the purpose of evaluating these elements where they can be of concern, for example, in coal combustion. When coal samples are prepared for analysis in accordance with this test method, the arsenic and selenium are quantitatively retained and are representative of the total mass fraction in the coal.
Scope
1.1 This test method2 covers the determination of total arsenic in the range of 0.7 ug/g to 12 ug/g and selenium in the range of 0.6 ug/g to 5 ug/g in coal.
1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
