摘要： Sulfate radicals (SO4 center dot-) based advanced oxidation processes (AOPs), with high efficiency and selectivity toward degradation of refractory organic contaminants, have captured increasing worldwide attention. Here, an efficient advanced oxidation process based on SO4 center dot- (i.e., a CRI/S(IV) process), induced by commercial reduced iron (CRI) powder-induced aqueous sulfite [S(IV)] activation for favorable degradation of refractory organics, is reported. The CRI/S(IV) coupled system efficiently decomposes rhodamine B (RhB) and 4-chlorophenol (4-CP) at weakly acidic and even neutral pHs. The distributions of active sulfur and iron species distribution in the CRI/S(IV) system were investigated and implied that HSO3-, FeHSO3+ and FeSO3+ were the main active species for S(IV), Fe(II), and Fe(III), respectively. In addition, radical quenching experiments show that both SO4 center dot- and hydroxyl radicals ((OH)-O-center dot) are present in this CRI/S(IV) system with SO4 center dot- as the dominant reactive radical for contamination removal. Furthermore, this novel process surpassed both CRI/Oxone and CRI/persulfate systems towards the organic degradation. This work might provide an implication for an efficient practical route for SO4 center dot- activation for wastewater decontamination, particularly for sulfite contaminated wastewaters with recalcitrant organic contaminants.
