ADSORPSI ZAT WARNA BIRU METILENA OLEH LEMPUNG BENTONIT AKTIF
ABSTRACT: Study on bentonite
adsorbent properties such as benthonite
optimum activation condition, afect of sulfic
acid consentration, activation
temperature and activation
time to decolorization of methilne
Blue has been
conducted. The study
was started by
activation of bentonite
upon methylene blue. The data was analysis by statistical method : Least Significant Difference (LSD or
BNT). It is
found that the
mass of bentonite
significantly effected (P
< 0,01) on the
decolorization percentage of
methylene blue. The
optimum condition of
adsorbtion showed that the concentration of activating agent
(sulfic acid) was 20%, activation temperature at 110oC and activation time
was 30 minutes.
On this optimum
condition, the bentonite
absorbed methylene blue up to
93.30% .
