The adsorption of dyestuffs from aqueous solutions using activated carbon. iii. intraparticle diffusion processes

The rate of dye removal from aqueous solution has been found to vary linearly with the square root of time for much of the adsorption period. A rate parameter, k, has been defined to explain intraparticle diffusion on a quantitative basis. This rate parameter has been correlated against the process variables thus providing useful design data.
