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
