Abstract

A wide range of experimental studies are reported for the adsorption of phenol and p-chlorophenol onto activated carbon-Type Filtrasorb 400-in an agitated batch adsorber. A model has been used to determine the external mass transfer coefficient for the systems and the effect of several experimental variables have been investigated: these include agitation, initial pollutant concentration, carbon mass, carbon particle size and solution temperature. The mass transfer coefficient has been correlated in terms of the dimensionless Sh/Sc^0.33 against each variable. The Sherwood number, Sh = k_fR/D_mol, relates the external mass transfer coefficient k_f to particle radius, R, and molecular diffusivity, D_mol. The Schmidt number, Sc, is the ratio of kinematic viscosity, v, to molecular diffusivity. A few results are also reported for the adsorption of sodium dodecyl sulphate and mercuric ions onto activated carbon.
