Catalytic oxidation of TrBP was tested by using five non-heme Fe(III) complexes.
The mer-[FeCl3(terpy)] had the highest capability to TrBP degradation with KHSO5.
DBQ was detected as a major byproduct and further degraded to organic acids.
15% of the degraded TrBP was mineralized to CO2 in mer-[FeCl3(terpy)]/KHSO5 system.
The mer-[FeCl3(terpy)] was activated by forming peroxide complex with oxygen donor.
