Standard Test Method for Determining Acid-Extractable Content in Activated Carbon by Ashing

Importancia y uso:

4.1 The quantitative determination of acid-extractable content is useful in evaluating activated carbon samples that contain acid-soluble impurities. These acid-soluble impurities can affect applications of activated carbon.

4.2 Limitations of Method—Hydrochloric acid is used in this test method as the extracting acid. All elements or compounds present in the activated carbon sample, which can be acid extracted, are assumed to form water-soluble chloride salts. Hydrochloric acid may not solubilize all impurities of activated carbon.
