Oxidisation strength of Photo-Catalytic Oxidation and Hydroxyl Radicals

Helping to destroy waterborne organisms

 

 
To compare the oxidation strength of the two AOP reactions; Photo-Catalytic Oxidation and Hydroxyl Radicals a comparison table can be seen below. The table shows the Reduction Oxidation (Redox) values which is the relative oxidation strength of the common oxidising systems available and clearly demonstrates that none can compare with the Titanium AOP.
