Effect of SIV dose on TCE degradation in BiOBr/TCE/SIV (photocatalyst/contaminant/reagent) system under simulated sunlight (a), the relationship between SIV dose and the percentage of TCE removal at t = tfinal (b), and the relationship between SIV dose and initial degradation rates (r0) (c). Conditions: [TCE]0 = ~ 0.25 mM, BiOBr dose = 1 g/L, and no pH control. The fitted model equation in c is r0= a * x/(b + x), where x is SIV dose (mM), a = 0.0055 (mM/min) and b = 0.42 (mM)
