Standard Test Method for Water Solubles in Activated Carbon

Significance and Use

In certain applications, the ash, color, conductivity, or pH of the finished activated carbon product may be influenced by the quantity of water solubles it contains. This water solubles test provides a relative indication of the quantity of soluble materials that may be extracted from various activated carbons.


1.1 This test method covers the determination of the water soluble content of (unused) granular and powdered activated carbons. Water solubles are materials that can be extracted by distilled water under reflux conditions and are expressed as a percentage of dry carbon weight.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
