Adsorption Kinetics of Cationic Dyestuffs on to Natural Clay
A three-step model has been proposed for the adsorption of cationic dyestuffs (Basic Blue 69 and Basic Red 22) from aqueous solutions on to natural clay. The rate of adsorption is controlled initially by the boundary layer film and an external mass-transfer coefficient K s has been determined for th...
