The present disclosure relates to a durable chemical treatment to enhance the adsorbency of activated carbon, which may be exposed to liquids such as rain, sweat, water, and the like. The treatment comprises a fluorocarbon that is applied at low add-on levels (that is, between about 0.1% and about 5%). The treated activated carbon is useful in a number of applications, including air filters, gas masks, solvent recovery devices, and chemical and biological protective gear. |
