abrasionhardness number: relative measure of the ability of granular or pelletized activated carbon to resist at trition during handling and use.

Absorption:: a process in which molecules are taken up by a liquid or solid and distributed throughout the body of the liquid or solid. Activated carbons do not absorb other materials (impurities).

Activated carbon: a family of carbonaceous materials manufactured by processes that develop an internal pore structure with adsorptive properties.

Iodine number: mgl, the amount of iodine adsorbed by one gram of carbon at equilibrium with a 0.02n iodine concentration filtrate.

Mesopore: in activated carbon, a pore having a diameter between 20-500 angstroms.

Macropore: in activated carbon, a pore having a diameter greater than 500 angstroms.

Micropore: in activated carbon, a pore having a diameter less than 20 angstroms.

Reactivation: the act of restoring adsorptive character to a contaminated activated carbon by a process similar to the original activation process.

Surface area (b.e.t.): the total surface area of a solid calculated by the b.e.t. (brunauer, emmett, teller) equation, from nitrogen adsorption or desorption data obtained under specified conditions; square meters per gram.
