EUROPACAT IX - Catalysis for a Sustainable WorldA
biosorption
system
for
the
removal
of
hexavalent
chromium
from
contaminated
effiuents
that
allows
the
reutilization
of
the
recovered
supports
as
catalysts
is
proposed.
The
system
consists
of
Arthrobacter
viscosus
bacterium
supported
on
NaY
zeolite.
After
the
treatment
of
the
effiuents,
the
metal-zeolite
can
be
used
in
oxidation
reactions.
This
work
reports
the
optimized
biotreatement
conditions that
lead
to
Cr-loaded
in
Na
Y zeolite,
which
was
tested
as
catalysts
in
the
liquid-phase
oxidation
of
cyclohexene.
A
comparison
is
made
with
a Cr-NaY
zeolite
prepared
by
the
usual
