ASTM D3838 – Standard Test Method for pH of Activated Carbon
Description:
Significance and Use
4.1 When a fluid containing an adsorbate is passed through a bed of activated carbon, chemical reactions may take place between the activated carbon, its other noncarbonaceous constituents, and the adsorbate-containing fluid. The pH of the carbon may be a significant parameter of such a reaction and therefore may be an important characteristic of the carbon.
Scope
1.1 This test method covers determination of the pH of a water extract of activated carbon.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
