Study of Reversible Ion-Isotopic Self Diffusion Reaction Kinetics Using 82Br as a Radioactive Tracer Isotope

Abstract

Radioactive tracers as a sensitive analytical technique have been
used to study the reversible ion-isotopic self-diffusion reactions. In
forward self-diffusion reactions, the ion exchangers in bromide
form were equilibrated with bromide ion solution (labelled with
⁸²Br as a radioactive tracer isotope) in the concentration range of
0.005-0.100 M. In reverse ion-isotopic self-diffusion reactions, the
labelled ion exchangers in the range of 0.7500-1.2500 g were equilibrated
with 0.0100 M bromide ion solution concentration. The results
of reversible ion-isotopic self-diffusion reaction indicate that
under identical experimental parameters, the reaction rates (in
min^-1) are calculated to be nearly same, indicating that forward and
reverse ion-isotopic self-diffusion reactions are complementary to
each other.
