Application of non destructive radiotracer technique for characterisation of industrial grade ion exchange resins Indion-850 and Amberlite IRA-400

The characterisation of industrial grade ion exchange resins Indion-850 and Amberlite IRA-400 was done by application of tracer technique using 82Br as a radioactive tracer isotope. The study on characterisation was performed to investigate the performance of the two industrial grade ion exchange resins under different process parameters like concentration of exchangeable ion solution, volume of resin beads and temperature of exchanging medium. The results obtained indicates that amount of bromide ion exchanged (millimoles) initial rate of bromide ion exchanged (millimoles/min) increases with increase in process parameters and are higher for Amberlite IRA-400 as compared to Indion-850 resins. On the basis of the characterisation results it appears that Amberlite IRA-400 is far more superior than Indion-850 for various industrial and technological applications. (author)
