| dc.description.abstract | Dye is an important chemical that present in our life. It can be used in textile, plastic,
leather, paper industries as additives. Azo dye with complex chemical structure that causing
it hardly can be removed, has accounted for 50% of all the commercial dye. Ozonation
process, with the utilization of ozone, can decolourize the dye by mineralizing it to become
smaller fragments, which are not harmful to the human being. Advanced oxidation process
in the other way can enhance the decolourisation process of the dye by using H2O2 that can
fasten the cleavage of the ozone. There are several analytical experiments to determine the
efficiency of the treatment process, which include COD test, BOD test, UV-Vis test and
also FTIR test. Those dyes that have been selected are Reactive Red 120, Reactive Black 5,
Reactive Green 19 and Remazol Brilliant Blue. They are selected since they are usually
been used in the factory industries. They show different results in the test with their
different complexity in chemical structure. Reactive Green will be the easiest type of dyes
to be decolourised whereas Reactive Red is the hardest. Advanced Oxidation Process can
perform better than ozonation. There will have complete degradation of azo bond with
naphthalene and benzene ring unable to be degraded completely at the end for both
processes. | en_US |
