Pemanfaatan Limbah Lumpur Industri Crumb Rubber Sebagai Adsorben Ion Cr(VI) yang Diaktivasi dengan H3PO4
Abstract: Utilization of
sludge waste from wastewater treatment system using active sludge systems of
Crumb Rubber Industry PT.Teluk Luas Lubuk Begalung Padang to be activated
carbon that was activated by H3PO4 as adsorbent of ions Cr (VI) has been done.
Characterization of activated carbon was conducted according to SNI
06-3730-1995, including the determination of iodine absorption, moisture
content, and the amount of carbon bound. Besides, this research was also
conducted using batch system treatment to activated carbon and inactivated
carbon, including pH, contact time, and initial concentration of solution. The
equation of Langmuir Isotherm was used to determine maximum capacity of
activated carbon adsorption to Cr (VI). Results showed that the absorption of
iodine was 48,26%, moisture content was 0.14%, and carbon bound was 24,925%.
The optimum pH, the contact time and optimum concentration respectively was pH3, 60 minutes and 50 mg/L
for an activated carbon adsorbent and
pH2, 120 minutes and 50 mg/L for
inactivated carbon adsorbent. The activator influenced to the adsorption of
Cr(VI). The determination of the optimum adsorption for activated carbon
adsorbent was 1,11 and 1,99 mg/g, meanwhile for inactivated carbon, it was 0,08
and 1,16 mg/g.
