Fig. 6From: Simulated solar light-driven photocatalytic degradation of trichloroethylene in water using BiOBr promoted by sulfite additionEffect of initial TCE concentration on the TCE degradation in BiOBr/TCE/SIV system under simulated sunlight (a) and the pseudo-first-order rate constant dependent on initial TCE concentrations (b). Conditions: the molar ratio of initial SIV concentration to the initial TCE concentration was fixed at 40, BiOBr = 1 g/L, and no pH controlBack to article page
