The rates of H+Mg2+ exchange at low solution concentration on several styrene sulfonic acid resins with either a macroporous or gelular matrix have been measured by the shallow-bed technique. The kinetics of Mg2+ uptake on macroporous and gelular resins were compared. The location of the liquid-solid interphase in the resin bead, where the ion diffusion rate controls the overall exchange rate, was estimated.
