Abstract
The Kinetic Model for Decolourization of Commercial Direct Blue 2 Azo Dye Aqueous Solution by the Fenton Process and the Effect of Inorganic Salts
Highlights
The textile industry is a major source of outflowing industrial wastewater due to more exhaustion of water during process operations
The mineralization of dyes generated by the textile industry is the main challenge and environmental concern (Holkar et al 2016)
The problem of a high toxic level of wastewater has been tried by Advanced Oxidation Processes (AOPs) (Sharma et al 2018)
Summary
The textile industry is a major source of outflowing industrial wastewater due to more exhaustion of water during process operations. This industrial wastewater contains chemicals such as alkalis, acids, dyes, surfactants and matter high in biochemical oxygen demand (Razzak & Hossain 2016). Large volumes of industrial wastewater with high scales of azo dyes (about 250 mg.L-1) are every day vacuous by many industries around the world in the surface water. The Fenton system is one of the most used techniques to degrade different organic pollutants such as azo-dyes by hydroxyl free radical generated from the hydrogen peroxide molecules reduction with Fe2+ ions at acidic pH (Jin et al.2017)
