Periodate (PI)-based advanced oxidation process has recently attracted great attention in the water treatment processes. In this study, solar irradiation was used for PI activation to disinfect waterborne bacteria. The PI/solar system could inactivate Escherichia coli below limit of detection (LOD, 10 CFU mL-1) with initial concentrations 1 × 106, 107, and 108 mL-1 within 20, 40, 100 min, respectively. •O2- •OH radicals contributed bacterial disinfection. These reactive attack penetrate cell membrane, thereby increasing amount intracellular oxygen species destroying defense system. damage membrane caused leakage K+ DNA (that be eventually degraded). Excellent disinfection performance systems achieved a wide range solution pH (3-9), coexisting humic acid (0.1-10 mg L-1) broad ionic strengths (15-600 mM). also efficiently Gram-positive Bacillus subtilis.

The elimination of gaseous sulfur-containing volatile organic compounds (S-VOCs) by a microbubble-assisted Fenton-like process is an innovative strategy. Herein, we established to eliminate malodorous microbubble CH3SH as representative S-VOCs, in which BiOCl nanosheets loaded on three-dimensional sponge were exposed (001) or (010) facets and induced interface reactions. Intriguingly, the significantly removed 99.9% CH3SH, higher than that macrobubble-assisted (39.0%). self-accelerating interfacial catalytic mechanism was in-depth identified situ ATR-FTIR, PTR-TOF-MS, EPR, DFT computational study. extraordinary performance lies enhancing dissolution/mass transfer gas/liquid phase tight contact between CH3SH-microbubbles 3D-BiOCl due low rising velocity (0.13 mm s–1) negative charge (−45.53 mV) CH3SH-microbubbles, well effective generation 1O2 activating enriched dissolved oxygen CH3SH-microbubble via electron-polarized sites sponge. Furthermore, transferred electrons H2O2 through electron-rich vacancy centers generate more •OH, thus achieving excellent performance. Overall, this study demonstrates enhanced S-VOC provides underlying mechanisms.
