Scholarcy highlights

  • The presence of pharmaceutical contaminants in the environment, as the result of incomplete degradation of conventional wastewater treatment processes has created serious environmental concerns
  • The ZnO/ICLT nanophotocatalysts were synthesized by sonoprecipitation method and characterized by XPS, TEM, BET and FTIR analysis
  • Pareto analysis confirmed that all 4 factors were impressive on the FRS degradation efficiency as the model response
  • The kinetic studies at optimum conditions showed a synergism effect between photocatalysis and ozonation for FRS degradation
  • The percentage of FRS mineralization increased to 88.7% in photocatalytic ozonation, while it was 40.6% by photocatalytic process
  • Experimental and economic studies indicated that photocatalytic ozonation by ZnO/ICLT could be an appropriate method for organic pollutant degradation due to highest mineralization rate and lowest energy consumption
