Laboratory experiments were conducted to determine sorption and desorption properties of ion exchange resins based on recovery rates. Dissolved nitrate (41.6 mM NO3−and 166.5 mM NO3−), ammonium (63.9 mM NH4+and 256.1 mM NH4+), phosphate (3.5 mM PO43–and 13.9 mM PO43–), and potassium (16.11 mM K+and 63.94 mM K+) were factorially combined and added at flow rates of 5 L at 3 and 9 h to an exchange resin / sand mixture. Six extractions with 1 M sodium chloride (NaCl) desorbed >90% of the added ions. Apparent recovery rates for nitrate (NO3-N) averaged 99% (±6), for ammonium (NH4-N) averaged 100% (±8), and for phosphate (PO4-P) averaged 109% (±6). Apparent recovery rates of potassium (K) were erroneously high (151% ± 12) and largely reflected analytical interference problems with the inductively coupled plasma (ICP) method. Concentrations of dissolved ions did not affect recovery rates of any studied ion.
