Abstract
The adsorption of four dyes namely Basic Blue 69 Basic Red 22 Acid Blue 25 and Acid Red 114 onto bagasse pith has been studied. A mass transfer model based on external mass transport and pore diffusion has been used to correlate experimental and theoretical concentration versus time data. The model is an analytical solution which may be applied to adsorption systems in which the operating line and tie lines all terminate on the saturation plateau of the equilibrium isotherm. A single external mass transfer coefficient and a single pore diffusion coefficient were sufficient to describe each system for several initial dye concentrations and several pith masses. The external coefficient were 9.0 x 10(-3) 8.0 x 10(-3) 1.0 x 10(-3) and 1.5 x 10(-3) cm(2) s(-1) the pore diffusivities were 5.5 x 10(-6) 2.5 x 10(-6) 2.2 x 10(-7) and 4.5 x 10(-7) cm(2) s(-1) for Basic Blue 69 Basic Red 22 Acid Blue 25 and Acid Red 114 respectively.
