State of Art and Perspectives in Catalytic Ozonation for Removal of Organic Pollutants in Water: Influence of Process and Operational Parameters

The number of organic pollutants detected in water and wastewater is continuously increasing thus causing additional concerns about their impact on public environmental health. Therefore, catalytic processes have gained interest as they can produce radicals able to degrade recalcitrant micropollutants. Specifically, ozonation has received considerable attention due its ability achieve advanced treatment performances at reduced ozone doses. This study surveys summarizes the application treatment, paying both homogeneous heterogeneous catalysts. review integrates bibliometric analysis using VOS viewer with systematic paper reviews, obtain detailed summary tables where process operational parameters relevant are reported. New insights emerging from homogenous applied for removal emerged discussed this paper. Finally, activities a variety catalysts been assessed chemical–physical such point zero charge (PZC), pKa, pH, which determine effect (positive or negative) processes.
