Standard Test Method for Total Ash Content of Activated Carbon

Importancia y uso:

4.1 In specific end uses, the amount and composition of the ash may influence the capabilities and certain desired properties of activated carbon.

4.2 Other automated methods for determination of ash content, such as combusting the carbon in a thermogravimetric analyzer (TGA) in flowing air or oxygen, can be used in place of this test method. A suitable method is described in Test Methods D7582. For determination of the ash content of activated carbon, follow the procedure in 13.5.3 of Test Methods D7582, with the exception that the furnace temperature in 13.4.3 shall be 650 °C ± 25 °C. The muffle furnace method shall be considered the reference test method.
