Carbon Tetrachloride

Carbon Tetrachloride Activity (ASTM D3467) measures the loading of carbon tetrachloride, weight percent on carbon, at concentrations near saturation in the air. Essentially, the method is a measure of the pore volume of the activated carbon and is primarily used as a quality assurance test for the production of activated carbon.

The Carbon Tetrachloride Activity has been replaced by the Butane Activity (ASTM D5742) test due to the ban on carbon tetrachloride.  CCl₄ activity = 2.55 x the Butane Activity.
