Abstract

This study aims at determining the influence of activated carbon masses of Sonokeling wood on the absorption of heavy metals of chromium and zinc from simulated waste using Batch method and the influence of simulated waste concentrations of Cr and Zn on the activated carbon absorption of Sonokeling wood. This research was conducted by using Batch method in which an activated carbon was put in simulated waste and then stirred continuously for 15 minutes. After that, the waste was settled for 30 minutes, taken the clear liquid only and filtered. This treatment was repeated each time with varied activated carbon masses of 5grams, 10grams, 15grams, 20grams, and 25 grams. Simulated waste concentrations were varied at 0.01 M, 0.02 M, and 0.03 M. To determine the activated carbon absorption of Sonokeling wood in the simulated waste, Cr and Zn were analyzed by using AAS. Research results showed that the activated carbons affected the efficiency of simulated waste absorption of Cr and Zn. The absorption efficiency for Cr waste tended to increase with absorbent mass increases in the activated carbon masses of Sonokeling wood of 16-20 with the highest evaporation rate at the mass of 15 grams, (55.4 1.0) % and the EP decrease occurred at the mass of 25 gr. The lowest absorption efficiency occurred at the mass of 5 grams that was equal to (5.1 1.0) %. Keywords : activated carbon, adsorption, Cr and Zn Year : 2009
