6 specific surface area, pore volume, average pore diameter
6.1 Principles
Particles placed in the gas, the surface (including the outer and internal through-hole surface) at a low temperature physical adsorption occurs. When the adsorption reaches flat
The equilibrium adsorption pressure and the amount of adsorbed gas are measured, and the saturated adsorption of the monomolecular layer is obtained from the adsorption isotherm according to the BET equation.
And the specific surface area of the sample is calculated. The pore diameter of the sample can be calculated from the desorption isotherm according to the Kelvin equation.
6.2 Instruments, equipment and materials
6.2.1 physical adsorption instrument. in the liquid nitrogen temperature, the nitrogen adsorption.
