Samarium
(III)
and
promethium
(III)
were
studied
by
chronopotentiometry
in
a
molten
LiCl-KC1
eutectic.
Tungsten
electrodes
were
used
to
avoid
alloying
effects
encountered
with
platinum
electrodes.
Adsorption
phenomena
were
observed
which
prevented
the
study
of
any
kinetic
effects.
The
quarter
wave
potentials
were
measured
as:
Sm(III)
=
0.95
