RES³T - Rossendorf Expert System for Surface and Sorption Thermodynamics

“Best fit” intrinsic constants, site density, and surface area (Table 1) were determined to minimize residuals between measured and predicted silica sorption densities.

The best fit surface area for the model is about 10 times higher than is reported elsewhere (18) for Fe(OH)₃, possibly due to an overestimate of electrostatic interactions between sorbed anionic silica dimers and charged surface sites in the overly simplistic diffuse layer model.

optimized surface area = 6.49E+03 m²/g
