“…At the same time, conventional treatment methods fail to degrade the pollutant as biological treatment is ine cient towards decomposition due to complex structure of the pollutant. On the other hand, AOPs have emerged as a promising approach towards treatment of such recalcitrant organic pollutants (Yadav et al 2022). The application of AOPs is reported successful in treatment of wastewater generated from pharmaceuticals (Verma and Haritash 2019), textile (Sharma et al 2016;Pipil et al 2021), pesticide, pulp and paper sector (Cameselle and Gouveia 2016) etc.…”

Chlorophenols have significant environmental concern owing to their toxicity, carcinogenicity and bioaccumulation potential, especially in the aquatic environment. Inefficient treatment of industrial effluents and discharge of partially treated wastewater further aggravates the environmental and health issues. Degradation of 2,4,6-Trichlorophenol using photochemical oxidation (TiO2) has come up as a potential treatment option. The present study used Degussa P-25 nano-TiO2 at varying doses for the optimisation of treatment. An optimised dose of 250mg/l TiO2could remove 2,4,6-Trichlorophenol completely wi thin 210 minutes of reaction period. Addition of H2O2 to further increase the rates of treatment did not yield any benefit. It was observed that UV365exposure may be replaced by solar light but the reaction rate was lower compared to UV. Finally, the comparison of operational cost of UV photocatalysis, photo catalysis with H2O2, and solar photocatalysis revealed the cost of US $ 0.27 per litre, 0.30 per litre, and 0.16 per litre, respectively, thus making solar photocatalysis the best option, but for lower volumes of wastewater. It was concluded that photocatalytic oxidation can be a sustainable treatment option for degradation of 2,4,6-TCP considering its benefits to environment and health.
