Fixed‐bed kinetic studies were made for Fe +++ — H + exchange, with perchlorate as the anion, covering concentrations from 0.5 N to 2.0 N in total cation, flow rates of 5 ml./min. sq. cm. to 45 ml./min. sq. cm. bed depth of 25 to 60 cm., and average resin particle diameters of 0.28 and 0.56 mm. The results are correlated on the assumption of internal diffusion as the rate‐controlling step and an essentially irreversible equilibrium.
