Abstract

The ability of Filtrasorb 400 activated carbon to absorb Astrazone Blue (basic) and Telon Blue (acidic) dyes using batch equilibria and fluidized beds was studied. The carbon adsorbs between 30% and 80% of its own weight of dye at equilibrium depending on dyestuff type and adsorbent particle size. The effects of adsorbent particle size and dye flowrates were studied in fluidized bed systems. Overall solid phase mass transfer coefficients were determined and external diffusion mass transfer coefficients were correlated against Reynolds number.
