	<span lang=\"EN-US\">Oxidation by Fenton like reactions
(Fe<sup>3+</sup>/H<sub>2</sub>O<sub>2</sub>) is economically process for destructive hazardous pollutants in
waste water. The effects of different parameters such as, amaranth red dye,
ferric chloride, hydrogen peroxide concentrations, pH value of solution,
temperature and the presence of inorganic ions (carbonate, nitrate, chloride)
on oxidative decolorization of amaranth were investigated. Amaranth degradation
by (Fe<sup>3+</sup>/H<sub>2</sub>O<sub>2</sub>) reagent was found to follow first order kinetic model. Under
optimum condition, pH = 2.6 and [FeCl<sub>3</sub>] = 3.75 ¡Á 10<sup>-4</sup> mol</span><span lang=\"EN-US\"><sup></sup><sub></sub><sub></sub><sup></sup><sub></sub><sub></sub><sub></sub><sup></sup><span style=\"font-family:Verdana;line-height:23px;white-space:normal;background-color:#FFFFFF;\"><span style=\"white-space:nowrap;\">¡¤</span></span></span><span lang=\"EN-US\">dm<sup>-3</sup>, the amaranth in
