The internal surface area of a carbon is usually determined by the BET method (Brunauer, Emmett and Teller).This method utilizes the low-pressure range of the adsorption isotherm of a molecule of known dimensions (usually nitrogen).<\/p>\n
This region of the isotherm is generally attributed to monolayer adsorption.<\/p>\n
<\/p>\n
<\/p>\n
Thus, by assuming the species is adsorbed only one molecule deep on the carbon\u2019s surface, the surface area may be calculated using the equation:<\/p>\n
S = XmNA\/M<\/p>\n
<\/p>\n
Most manufacturers will specify the surface area of their products but as with CTC activity, it does not necessarily provide a measure of their effectiveness, merely demonstrating their degree of activation. It is also impractical to utilize surface area measurement as a means of quality control since this is a very lengthy procedure.<\/p>\n","protected":false},"excerpt":{"rendered":"
