<P>PROBLEM TO BE SOLVED: To provide a method for measuring easily a surface fractal dimension showing the abundance of pores, especially submicron pores, on the surface of a carbon material, especially activated carbon. <P>SOLUTION: Metal atoms are adsorbed onto the carbon material, and activation energy for atomization is determined through temperature change measurement of a graphite furnace atomic absorption signal of the atoms. Then, the fractal dimension is determined from a saturated adsorption amount of the atoms. It can be determined from the values whether the atoms are adsorbed into submicron pores or not, namely, how many submicron pores exist in the carbon material. Serviceability is shown by using gold atoms as an example. <P>COPYRIGHT: (C)2007,JPO&INPIT |
