Removal of phenol from Synthetic Waste Water by Fenton Method with Taguchi Test Design

Phenol has a special importance among the various pollutants found in most industrialwastewater. Phenol is a hydrocarbon that the US Environmental Protection Agency hasplaced it in the category of first-class pollutants. This material and its derivatives are used invarious industries such as resin and plastic manufacturing industries, paints, pesticides, pharmaceuticals,petroleum refineries, petrochemicals, coal mines, steel and aluminum and leadindustries, detergents, artificial textiles and leather. And is therefore considered as an importantpollutant in the sewage sludge mentioned above [1]. Phenol with the general formulaC6H5OH is also known as hydroxyl benzene and carboxylic acid. Phenol is one of the mostimportant organic compounds used in industry, which is used in many industries as a raw material[2]. In this study, removal of phenol from effluent by Fenton oxidation method was investigatedusing iron catalyst and H2O2 addition. Different conditions and quantities used inthe experiment were designed using Taguchi technique, and finally, the optimal values oftemperature, iron catalyst and the amount of H2O2 was used. The optimal results of these valueswere obtained at 25 °C, pH = 3, H2O2 equal to 5 g, and iron amount 5 g. Finally, underoptimal conditions, by analyzing the actual sample, the removal of more than 80% of the phenolcontent We were in the wastewater. This method is one of the best methods for removingphenol from industrial effluent, due to its cost-effectiveness and rapid analysis and availabilityof used materials.
