To investigate the effect of TBA on the PEC degradation of organics, 100 mg L−1 TBA was added at the concentration ratio of 1 1 into 100 mg L−1 different organics to form the organic-TBA mixture with a total concentration of 200 mg L−1.
In contrast, the yield of other solvents is 12% (DMF), 9.5% (NMP), 8.4% (tBA), 4.5% (IPA), and 1.5% (H2O), far below that of the former.

Open image in new window Fig. 7 I t curves obtained from the PEC degradation of 100 mg L−1 TBA and 100 mg L−1 a glucose b phthalate containing TBA of different concentrations, respectively.
This phenomenon may due to the instance photocurrent responses of TBA are not dominant in the mixture; for illustration, the I 0 value of 100 mg L−1 TBA is 2.085 × 10−4 A, much smaller than that of glucose (2.330 × 10−4 A) and phthalate (2.107 × 10−4 A) at the same concentration.
Comparing the I t curves of 100 mg L−1 glucose and phthalate, respectively, containing none and 100 mg L−1 TBA, it can be seen that there are no significant differences at the early stage, later the photocurrent values of mixture that containing organic and TBA become higher than that of organics alone, the peak area extends, and the time to achieve the stable state prolongs.
Where C is the absorbance value of the fully oxidized control, and E is {(A532 + TBA)–(A532– TBA)}.
