Abstrak | Chrome is a substance belong to high toxicity heavy metal group which can cause both acute and chronic poisoning. One of the methods that can be used to reduce its concentration is biosorbtion with bagasse biomass. The objectives of the study were to understand the chrome concentration before and after absorbed, as well as to understand the amount of the most effective biomass. The study was an experimental with three treatments of which consisted of eight repetitions. The sample was synthetic liquid waste and the treatment absorbent was bagasse biomass which was processed as activated carbon of 10, 15, and 20 grams weight. The chrome concentration were measured by using AAS method. The results showed that the chrome concentration before treated was 10,196 mg/l, and the average of the reduction from the three absorbents weight were: 0.174 mg/l, 0,099 mg/l, and 0,011 mg/l respectively. It can be concluded that there were reduction differences amongst the three treatments, and 20 gr absorbent was the most effective one (99.88 % reduction). It is advised for further study to apply the bagasse for processing liquid waste from industrial activities. |
