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 110o C and
activation time was 30 minutes. On this optimum condition, the bentonite absorbed methylene
blue up to 93.30% .
