Langmuir and BET plot analysis gave the desired results. The pore size and pore volume were also found in the desired range.The outgas time was 6 hrs.The method used for the BET surface analysis is physisorption method. The model of the BET surface area which describes the quantity of adsorbed gas as a function of the relative pressure, p/po.In the BET suface area analysis we use the area per molecule for the calculation olf whole BET surface area.
