TL;DR: In this article, the authors observed the concentration profiles (concentration in fluid phase, versus abscissa in bed from inlet) in the adsorbent bed of Figure la, when the adorbent was initially clean and received a feed of constant concentration in some adsorbable species A (the solute).
Abstract: Let us observe the concentration profiles (concentration in fluid phase, say, versus abscissa in bed from inlet) in the adsorbent bed of Figure la, when the adsorbent is initially clean (1) and receives a feed of constant concentration in some adsorbable species A (the solute).
