Abstract
Sorption behavior of phosphoric acid on the weak base resins Amberlite IRA-93 and Dowex WGR-2 is reported. Studies on sorption equilibria an d dynamics reveal anomalous sorption behavior as compared to sorption of strong and weak monobasic acids. A mathematical treatment is develo ped to correlate the experimental data on sorption dynamics. An altern ative type of mechanism is also proposed based on the results obtained in this work to explain the anomalous sorption behavior of phosphoric acid on weak base resins.
