Method Description:
Samples are weighed into centrifuge tubes, and water or an aqueous solution is added. The tubes are covered, and the sample is dispersed in the liquid by shaking. The dispersion is allowed to equilibrate for 20 minutes with repeated shaking every five minutes. The tubes are centrifuged, the clear liquid is poured off, and the contents of the tube are weighed. The water retained by the sample is calculated from the recorded weights.
Additional Information:
The solvent used can be water or an aqueous solution of salts, weak acids, or weak bases, depending on the application.
