Abstract

Gum acacia based nanocomposite ion exchanger has been fabricated using simple sol–gel method. The effect of biopolymer concentration on ion exchange capacity has been studied. The GA/CeMoPO4 nanocomposite ion exchanger has been well characterized using various techniques as FTIR, XRD, SEM and TEM. The GA/CeMoPO4 showed better ion exchange capacity of 1.04 meq/g in comparison to its inorganic counterpart GA/CeMoPO4 (0.65 meq/g). The various physicochemical properties including thermal stability, elution behavior and pH titrations were studied in detail. The photocatalytic nature of GA/CeMoPO4 and CeMoPO4 were investigated using methyl violet as test dye. The GA/CeMoPO4 showed 86% of methyl violet photodegradation in 2 h of illumination.
