Ash Content of Activated Carbon
Ash content: This test provides the total ash content and in some cases, a more detailed analysis of the ash is needed. The ash content increases in direct proportion to the degree of activation and it can be used to determine the raw material used to produce activated carbon. For instance, coconut shell carbons contain 1-3 wt% ash, whereas coal-based activated carbons have 6- 20 wt% ash content.
