Effect 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 controlled
