This Part of BS 4359 describes recommended methods for the determination of metal surface area using gas adsorption. They are suitable for supported monometallic catalysts where the metal surface area differs from the total surface area.These methods may also be suitable for other metal catalysts, such as some Raney materials. Specific recommendations are given for the determination of metal surface area of nickel, palladium, platinum and copper. Information on the extension of these methods to other metals in Groups VIII and IB of the periodic table is given in Annex A. Recommendations are made regarding the most suitable gas and test methods for a given metal/support combination. Both chemisorption methods and those which employ surface reaction (or titration) are described. Volumetric or flow techniques may be used todetermine the amount of gas chemisorbed. Recommendations are given to correct for any reversible adsorption detected using the volumetric technique.
