Fig. 9From: Simulated solar light-driven photocatalytic degradation of trichloroethylene in water using BiOBr promoted by sulfite additionEffect of SIV reinjection on cycling performance of BiOBr in degrading TCE in the presence of SIV under simulated sunlight. Conditions: TCE alone (a) and both TCE and SIV (b) was reinjected at 2nd and 3rd cycle. [TCE]0 = ~ 0.1 mM, [SO32−]0 = 4 mM, and BiOBr = 1 g/L. a The amount of TCE injected at the start of each cycle increased the concentration of TCE by 0.1 mM. b The amount of TCE and SIV injected at the start of each cycle increased their concentrations by 0.1 mM and 4 mM, respectively. In all experiments, the solution pH was not controlledBack to article page
