Exchange constants of Al(III) and Fe(III) on Dowex 50W-X8.
The exchange constants tor Al(3+) and Fe(3+) ions on the cation-exchange resin Dowex 50W-X8 (H(+)-form) are reported. A batch method of equilibrium at room temperature was used to determine these constants, which are Al(3+) + 3HR right harpoon over left harpoon AIR(3) + 3H(+), K = 1.66 Fe(3+) + 3HR right harpoon over left harpoon FeR(3) + 3H(+), K = 2.19 R denoting the resin.
