Abstract
The rate of adsorption of Astrazone Blue, a basic dye, on Sorbsil Silica has been studied. The parameters studied include particle size, initial dye concentration, agitation and dye solution temperature. The rate controlling step is mainly intraparticle diffusion, although a small boundary layer resistance is experienced. The activation energy for the adsorption of Astrazone Blue on silica is 13.2 ± 0.6 kJ kg-1. The diffusion coefficients vary from 9 × 10-9 cm2 s-1 at 20°C to 10 × 10-8 cm2 s-1 at 82°C.
