Abstract

This project is about degradation oforganic compound in the waste water by using
chemical. It is a method ofoxidizing organic compounds in aqueous solution by using
hydrogen peroxide (H2O2). Concentrations oforganic compounds are very high in the
waste water. So oxidizing agent such as hydrogen peroxide which has a higher
oxidizing potential is used in degradation oforganic compounds in waste water.
Hydrogen peroxide is used as the oxidizing agent because it is cheap and easy to handle.
Oxidation removes harmful and toxic substances. These methods are very important
because can degrade organic pollutants to non toxic substance such as carbon dioxide
and water.
The degradation ofdye is chosen as the organic compound to be tested on. Malachite
Green Oxalate is the tested dye. Pollution ofwater by dyes is a serious problem in the
developed countries. Many industries use dyes to color their products. These highly
colored components when discharged with wastewater in the water bodies stop
reoxgenation capacity ifthe receiving water and cut-off sunlight, thereby upsetting
biological activity in aquatic life. Furthermore, the expanded use ofdyes has shown that
some ofthem and some oftheir reaction products, such aromatic amines, are highly
carcinogenic. The removal ofdyes (color) from wastewater is, therefore, a challenge to
the related industries. The parameters mat are tested on are: (i) The initial dye
concentration (ii) The hydrogen peroxide concentration
(iii) Stirring/ Speed (iv) Temperature
The manipulated variable is the concentration ofhydrogen peroxide. The concentration
is varied and the corresponding level ofdegradation is tested at constant time. The
initial dye concentration and the temperature is also varied to investigate the effect on
dye degradation. The concentration ofdye at certain time is measured using UV Spectro
