AB  - Industrial units based on chemical processes-the textile and paper industries-are 
      major sources of chlorophenols in the environment, and chlorophenolic compounds 
      persist within the environment for a long time with high toxicity levels. The 
      photo-assisted Fenton's and photocatalysis processes were investigated for the 
      degradation of chlorophenols in the present study. Response surface methodology 
      was employed to get optimised conditions for photocatalysis and photo-Fenton 
      process-governing factors, thus, yielding a profound removal efficiency. Under 
      optimised conditions, with a photocatalyst dose of 0.2 g/L, oxidant concentration 
      of 10.0 mM and pH 5.0, complete removal of 2,4-dichlorophenol (2,4-DCP) was 
      observed in 210 minutes in photocatalytic treatment. In the case of the 
      photo-Fenton process, at an H(2)O(2) dose of 5.0 mM and Fe(2+) concentration of 
      0.5 mM, the organic pollutant was eliminated within 5 minutes of reaction time 
      under acidic conditions (pH 3.0). The RSM model reported the perfect fit of 
      experimental data with the predicted response. Among different isotherm models, 
      the Langmuir isotherm was the best fit. The process followed pseudo-first order 
      rate kinetics among various kinetics models. For the obtained optimised 
      conditions, sonication and solar energy-driven processes were incorporated to 
      study enhanced mineralisation. The solar-assisted Fenton process reported maximum 
      mineralisation (90%) and cost-effective ($0.01/litre for 100 mg/L 2,4-DCP) 
      treatment among different hybrid oxidation processes. The work provides insight 
      into harnessing the naturally available solar energy, reducing the overall 
      treatment cost and opting for a sustainable treatment method.
