Surface area of modified mesoporous silicates have been quantitatively determined using x-ray diffraction patterns and chemometric methods. The modified mesoporous silicate samples with varying surface area (223-1164 m(2)/g) were synthesized and their effective surface areas were calculated by the Brunauer-Emmett-Teller (BET) method using their nitrogen adsorption isotherms. The x-ray diffraction patterns of the samples were measured. The chemometric techniques were used to model the diffraction patterns as a function of the calculated surface area. The prediction results of the multiple linear regression (MLR) model was better than the partial least squares (PLS) model and both of the methods can be used for predicting the surface area of new mesoporous; samples
