Web14 hours ago · Question: i) Define and explain what the selectivity coefficient of an ion exchange resin is? A 100ml portion of a 1.00×10−3MKCl solution is equilibrated with 0.150 g of a strong cation exchange resin Rz−H+with a capacity of 4.02meq/g, and the potassium concentration in the supernatant solution is found to be 2.20×10−4M by flame atomic … WebJul 14, 2003 · The ion exchange capacity of CNas metal complexes increased to about three times that of free cyanide due to higher selectivity of metal complexes on the anion exchange resin.

WebI have seen some information that selectivity reversal will occur when the solution has high TDS e.g., sulphate will have a far higher affinity than chloride for a strong base anion resin within a solution with low TDS; however, at high TDS the affinity of these ions for the resin will be reversed - chloride will have a greater affinity than ...

WebFrom this equilibrium state, selectivity coefficients (equilibrium constants), can be defined based on the ratios of ions in solution vs. ions on the resin. Effectively, these selectivity … WebThe ZR Resin shows high selectivity for Zr, Ti and Nb over a wide range of HCl concentrations (0.01M – 10M), Fe(III) is strongly retained at low and elevated HCl concentrations, retention is weak from 1 – 6M HCl. As expected, the resin shows very little selectivity for Sc and Y, a separation e.g. of Zr WebSwelling: The hydration of the fixed ionic groups that increases with an increase in capacity to the limits imposed by the resin’s polymer network.
