Humans
are
the
only
producers
of
wastes
accumulated
in
nature.Treatment
technologies
developing
by
following,
analyzing
and
imitating
nature.Herbal
bioadsorbents
natural
substances
used
wastewater
treatment.In
this
study,
Malachite
Green
(MG)
was
removed
from
water
with
Verbascum
Thapsus
L.
(VTL).VTL
collected
Mount
Ararat
is
a
wild
invasive
plant.SEM,
BET
FTIR
were
to
determine
adsorbent
characterization.Experimental
design
made
surface
response
method
(RSM).Optimum
values
obtained
as
result
experimental
studies:
Adsorbent
mass
0.75g,
pH6.5,
initial

adsorbed
substance
304mg/L
contact
time
adsorption
40
minutes.It
determined
that
process
carried
out
accordance
Langmuir
isotherm
(R

=0.9997)
second-order

95%.As
thermodynamic
study;
Gibbs

(∆G)
found
be
negative
for
all
temperatures.According
results
at
end
it
VTL
an
effective
