| Abstract: | A series of breakthrough curves for the adsorption of Deorlene Yellow and Telon Blue on carbon have been used to test a kinetic model. The model is based on the unreacted core theory and assumes resistances due to external mass transfer and pore diffusion, and irreversible adsorption. The experimental and theoretical data are well correlated by the model at low dye flow rates, but the model was modified at high dye flow rates. The effective diffusivities are 4.0 × 10−10 m2 s−1 and 3.0 × 10−10 m2 s−1 for Deorlene Yellow and Telon Blue respectively. |
