Abstract:
The
adsorptive
ability
of
mUCIn
onto
hydroxyapatite
was
evaluated
based
on
its
adsorptive
amount
and
adsorptive
strength.
The
adsorptive
amount
was
determined
by
measuring
the
amount
of mucin
adsorbed
onto
hydroxyapatite
while
adsorptive
strength
was
determined
by
measuring
the
amount
of
mucin
remaining
adsorbed
after
rinsing.
I
The
amount
of mucin
adsorbed
onto
the
substrates
in all
cases
followed
the
order
Sigma
grade
HAP>
synthesized
HAP>
CHP
and
generally
increased
with
increase
in
the
amount
of adsorbent.
More
than
80%
of mucin
was
adsorbed
unto
HAP
with
or without
Ca
2
+
ion
pretreatment.
The
adsorption
isotherm
fitted
the
Langmuir
model
and
electrostatic
attraction
mechanism
is proposed.
