from aqueous solutions in a continuous flow fixed bed reactor using Dowex 50 W-X8 ion-exchange resin was conducted. The performance of the fixed bed sorption was evaluated using the concept of the sorption breakthrough process. Parameters characteristic of a fixed bed sorption such as breakthrough times,saturation times, critical reactor lengths, and lengths of mass transfer zone were inferred from......
