Assessment of the exchange parameters of Amberlite IR-45 (OH) resin from its elution with saturated Na2SO4

Abstract

Simple quantitative technique has been developed for assessing the exchange parameters of Amberlite IR – 45 (OH) using column chromatographic techniques from the displacement of exchangeable hydroxyl ions of the resin by sulphate ions. The results obtained showed retention time of 33min, retention volume of 56.5cm³, void volume of 18cm³, and exchange capacity of 41mmole/g and exchange site density of 2.4682 x 10²²sites /g.
