- Abstract
The study represents the evaluation of performance of structurally related resins Duolite ARA9366 and DuoliteA-378 exposed to UV radiations of wavelength λ=254nm and λ=384nm for 24 h in a UV Chamber and equilibrated separately with iodide ion solutions of different concentrations between temperature of 30.0°C - 45.0°C for 5 h the equilibrium constants (K) values for Cl-/I- reactions with temperature for Duolite ARA-9366 were decreased from 21.57 x 10-2 to 15.57 x 10-2 for resin degraded at UV radiation of 384 nm was lower than the decrease in K values from 26.22 x 10-2 to 19.92 x10-2 observed for the resin degraded at UV radiation of wavelength λ=254nm. Similar results were obtained for Duolite A378 .The UV degradation of the resin surfaces were recognized by SEM and IR. The high K and low enthalpy values obtained for Duolite ARA-9366 shows that Duolite ARA-9366 was more selective towards iodide ions in solution than Duolite A-378.
