ADSORPSI ZAT WARNA BIRU METILENA OLEH LEMPUNG BENTONIT AKTIF

Abstract

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% . Keywords: Bentonite, Methylene Blue, Activation, Decolorization
