Remediation of wastewater: Role of hydroxyl radicals

• The photocatalytic oxidation of wastewater.
• Coupling effect of different advanced oxidation processes.
• A basic mechanism and reactions involved during oxidation.
• The role of hydroxyl radical in the breakdown of the wastewater.
• COD, BOD and TOC analysis.

The photocatalytic oxidation of wastewater with TiO2 and coupling effect of different advanced oxidation processes onto the oxidation of wastewater has been studied. A basic mechanism involved during oxidation has been reported. The role of hydroxyl radical in the breakdown of the wastewater is elucidated through determining the degradation rates, kinetics, analyzing transformation intermediates and studies using computational chemistry methods. In order to realize a complete mineralization of wastewater COD, BOD and TOC analysis has been carried out.
