The degradation process was optimized using slurry photocatalysis where 96% degradation of 2Cl4NP was achieved in 120 min at optimized conditions of C0=50 mgL-1, pH=4, 0.75 gL-1 TiO2 and H2O2= 0.1 mL/200 mL. Degradation of 2Cl4NP was analyzed through HPLC along with UV-Visible spectrophotometer at 266 nm. The degradation of 68% and 52% of 2Cl4NP was attained in fixed-bed photocatalysis using cement and clay beads, respectively. The durability studies of cement and clay beads were carried out in terms of number of recycles. 97.19% degradation was obtained in a solar photo-Fenton process after 105 min at pH=3. Complete mineralization of 2Cl4NP was confirmed through reduction in COD along with the disappearance of the parent compound peak in HPLC chromatograms.</p></div>
