Fe(II) is an excellent promoter for advanced oxidation processes (AOPs) because of its environmental ubiquity and low toxicity. This study among the first to characterize reaction peracetic acid (PAA) with ion apply Fe(II)/PAA AOP degradation micropollutants. PAA reacts (k = 1.10 × 105-1.56 104 M-1 s-1 at pH 3.0-8.1) much more rapidly than H2O2 outperforms coexistent Fe(II). While alone showed minimal reactivity methylene blue, naproxen, bisphenol-A, significant abatement (48-98%) compounds...

Peracetic acid (PAA) is increasingly used as an alternative disinfectant and its advanced oxidation processes (AOPs) could be useful for pollutant degradation. Co(II) or Co(III) can activate PAA to produce acetyloxyl (CH3C(O)O•) acetylperoxyl (CH3C(O)OO•) radicals with little •OH radical formation, Co(II)/Co(III) cycled. For the first time, this study determined reaction rates of (kPAA,Co(II) = 1.70 × 101 6.67 102 M-1·s-1) (kPAA,Co(III) 3.91 100 4.57 ions over initial pH 3.0-8.2 evaluated 30...

Peracetic acid (PAA)-based advanced oxidation processes (AOPs) have shown broad application prospects in organic wastewater treatment. Alkoxy radicals including CH3COO• and CH3COOO• are primary reactive species PAA-AOP systems; however, their reaction mechanism on attacking pollutants still remains controversial. In this study, a Co(II)/PAA homogeneous AOP system at neutral pH was constructed to generate these two alkoxy radicals, different mechanisms with typical emerging contaminant...

Peracetic acid (PAA) is a sanitizer with increasing use in food, medical and water treatment industries. Amino acids are important components targeted foods for PAA ubiquitous natural waterbodies wastewater effluents as the primary form of dissolved organic nitrogen. To better understand possible reactions, this work investigated reaction kinetics transformation pathways selected amino towards PAA. Experimental results demonstrated that most showed sluggish reactivity to except cysteine...

Open-vocabulary object detection aims to provide detectors trained on a fixed set of categories with the generalizability detect objects described by arbitrary text queries. Previous methods adopt knowledge distillation extract from Pretrained Vision-and-Language Models (PVLMs) and transfer it detectors. However, due non-adaptive proposal cropping single-level feature mimicking processes, they suffer information destruction during extraction inefficient transfer. To remedy these limitations,...

The critical challenges of using electromembrane processes [e.g., electrodialysis and flow-electrode capacitive deionization (FCDI)] to recycle resources (e.g., water, salts, organic compounds) from wastewater are the fractionation dissolved ionic matter, removal/recovery components during desalination, membrane antifouling. This study realized simultaneous fractionation, dye (FDR) treatment dye/salt mixtures through a simple but effective approach, that is, carbon cloth-modified FCDI...
