✦ Synopsis

Abstrad-Based on the adsorption-rate equation derived in Part I of this investigation, a differential equation has been obtained for the prediction of the concentration distribution in activated carbon columns. This differential equation derived without the constant pattern assumption has been solved analytically. The solution includes both the transition region and the range of the constant pattern which is fully developed in a finite time and finite column length. The comparison of predicted data with experimental values indicates that film resistance has a considerable influence on the concentration history and should never be ignored.
