| Abstract The surface area of a local silicate rock was investigated using different methods after being thermally treated at 200, 400,600 and 800 C° to detect the optimum temperature of treatment. The study has disclosed that the optimum temperature of treatment was 600C° for its maximum surface areas as compared to others. The surface area of the thermally treated samples was determined by many methods including retention by ethylene glycol mono ethyl ether (EGME), adsorption from solution using PNP and MB as solutes as well as the adsorption from vapor phase using acetone vapor. These samples, however, exhibited good surface areas as compared to the untreated silicate .Also, the adsorption isotherm of PNP and MB of all samples were determined and found to be fit to Langmuir type of isotherm which refers to clear micro porous tendency | ||
