Abstract
Chloramphenicol (CAP) is found abundance in composition of water that hazardous
and cause harmful to human health if consume and to ecosystem. Therefore this study
is about the adsorption/removal of chloramphenicol by ordered mesoporous carbons
(OMC) using the Aspen Adsorption® simulation. First and foremost in the simulation,
the constant parameters need to be identified and manual calculated in the Microsoft
Excel such as isotherm parameters (IP) values, adsorbent and bed porosity, tortuosity
and the global mass transfer coefficient (MTC). The first simulation operation
condition are manipulating the initial CAP concentration (50, 100 & 200 mg/L) and
constant the bed height (2cm) and flowrate (10 mL/min). At 50 mg/L initial
concentration show the longest breakthrough (925 minutes) and exhaustion time (1600
minutes). For the changing in the flowrate (10, 20 & 30 mL/min), the longest
breakthrough and exhaustion time is at 10 mL/min which 925 minutes and 1600
minutes respectively. Vice versa for the effect of the bed height (2, 4 & 6 cm) on
adsorption, which show the longest breakthrough (2700 minutes) and exhaustion time
(4500 minutes) at 6 cm. In the simulation column adsorption studies, Thomas and
Yoon-Nelson model shows the highest R2 value (0.999) compared to Bohart-Adams
model (0.950-0.99).
