Efficient electrochemical degradation of TBP using a Ti/SnO 2-Sb/ F-PbO 2 electrode

A Ti/SnO 2 -Sb/F-PbO 2 electrode was applied to electrochemically oxidize tributyl phosphate (TBP). Under the optimal conditions, TBP removal reached 82.4 % in 80 min with an energy efficiency of 82.6 g kWh -1 . This method overcame some TBP biodegradation 's flaws such as narrow initial treating concentrations range and time- consuming. The degradation energy efficiency of our method ranges from 34.4 g kWh -1 to 379 g kWh -1 at different initial concentrations (0.5 -5.0 g/L), which is also far higher than that of a previous electrochemical treatment of TBP (0.13 g kWh -1 ).
