Batch experiments were conducted with strong-base anion exchange (SBA) resins using centrifugal stirrer devices to accurately determine intraparticle mass transfer coefficients (Ds) by reducing external mass transfer resistance. Nitrate was used as a model ion to validate the method and nitrate Ds were obtained for three SBA resins. This dataset is associated with the following publication: Smith, S., B. Gray, E. Hughes, L.
