Fuller's earth and fired clay as absorbents for dyestuffs external mass transport processes during adsorption

The kinetics of the adsorption of two dyestuffs, Astrazone Blue (Basic Blue 69) and Telon Blue (Acid Blue 25), onto fired clay and Fuller's earth have been studied. The rate of adsorption is controlled initially by the boundary layer film and an external mass transfer coefficient has been deter...

Description
Summary:The kinetics of the adsorption of two dyestuffs, Astrazone Blue (Basic Blue 69) and Telon Blue (Acid Blue 25), onto fired clay and Fuller's earth have been studied. The rate of adsorption is controlled initially by the boundary layer film and an external mass transfer coefficient has been determined for this process under the influence of a number of variables including agitation. initial dye concentration, adsorbent particle size, adsorbent mass and temperature.
