3.7 Nitrogen gas adsorption analysis and specific surface area
Accurate measurement of surface area and porosity of materials is
important in many applications such as nanosilver, metal-organic
framework and metal nanoparticles; Because by knowing the average
thickness of a molecule it is possible to calculate the surface occupied
by the molecule and measure the amount of material absorbed and the
total sample area. The table (3) for the nano-composite metal-organic
framework with different percentages (30, 10 and 50) of nickel ferrite,
surface area and pore volume are given.
