    Studies of the cation exchange system Fe+++-H+: I. Equilibrium studies (1959)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Equilibrium data are presented for the exchange of Fe+++ and H+ on a sulfonated polystyrene exchanger. The data cover solution concentrations from 0.05 N to 2 N in total cation for solutions having either nitrate or perchlorate ion as the common anion. The nitrate system shows irregular behavior because of complex ion formation, but for composition where such behavior is absent the equilibrium data can be correlated by equations based on the law of mass action. Equilibrium compositions for the perchlorate system can be correlated over the entire range studied by a single equation based on the law of mass action. Methods based on the law of mass action are presented for correlating or predicting equilibrium compositions for both systems.

    Studies of the cation exchange system Fe+++-H+: II. Rate studies in concentrated solutions (1959)

    Notes: 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.

    Notes: Equilibrium isotherms are presented for the cation exchange of copper and sodium on Dowex-50 resin in solutions from 0.01 to 4N in chloride content, and the equilibrium data are correlated on the basis of the Donnan equilibrium. Data are also given on the water content of the resin and the diffusible ions present in this water.

    Ferric ion removal from dilute acidic solutions by fixed-bed cation exchange (1956)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 2 (1956), S. 381-384

    ISSN: 0001-1541

    Notes: The removal of a trivalent ion (Fe+++) from acidic nitrate solutions by a fixed bed of Dowex-50 cation-exchange resin was studied at entering iron concentrations from 14 to 4 meq./liter, flow rates of 0.073 to 1.20 liters/(hr.)(sq. cm.), and bed sizes from 3.7 to 5.4 g. of dry resin/sq. cm. Acid strengths were below 0.45 N. The results were correlated is a relatively simple break-through equation based on the assumptions of an equilibrium extremely favorable to iron adsorption and liquid-film diffusion being the rate-controlling factor. The capacity of the resin for iron was dependent upon the acid concentration of the sulation.The results provide a design equation requiring a minimum of experimental work.
