Abstract

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.
