ASTM D3838

pH of Activated Carbon

Applicability: ASTM D3838 is a standard test method used to determine the pH of a water extract of activated carbon. It is applicable to various types of activated carbon to assess surface chemistry, which is critical for understanding reactions when fluids pass through a carbon bed.

Purpose: The purpose of ASTM D3838 is to measure the pH of the water extract of activated carbon to characterize surface chemistry. It helps determine if the carbon is acidic or basic.
