“…Many studies − have shown that ultraviolet (UV) light with a wavelength lower than 300 nm can effectively decompose peroxide to produce free radicals (see Table ). 254 nm short wave UV light and 185 nm vacuum ultraviolet (VUV) light are the two most used UV light sources in the field of photochemical advanced oxidation technologies (AOTs).…”

Emission of SO2, NO x , mercury (Hg), and arsenic (As) from flue gas has become a great public concern due to their hazards for human health and ecosystems. Simultaneous removal of multipollutants (two or more of SO2, NO x , Hg, and As) has good development prospects due to its simple system and low cost. Although many multipollutant simultaneous removal technologies have been developed, green oxidation absorption is one of the most promising technologies because it can not only make full use of the existing WFGD devices, but also its treatment process is clean. This review analyzes the latest research advances in the removal of SO2, NO x , Hg, and As from flue gas using green oxidation absorption technologies. The performance, mechanism, and kinetics of SO2, NO x , Hg, and As removal are reviewed. The merits and drawbacks of these green oxidation absorption technologies and the potential research directions are commented on. This review indicates that each technology has its own advantages and disadvantages in terms of removal efficiency, cost, reliability, and product post-treatment. Photochemical and electrochemical removal technologies have a high free radical yield and pollutant removal efficiency, but they have complex systems, high energy consumption, or unreliable systems. Metal oxide-activated peroxide oxidation technology has a good prospect due to its simple process, low device requirements, and recyclability of catalysts. However, it also has shortcomings such as a low free radical yield and easy deactivation of catalysts. Other technologies also have some disadvantages, such as high cost, low free radical yield, difficult separation of products, complex equipment, and/or low reliability. Synergic use of multitechnologies may be a promising strategy because it can make up for the shortcomings of each technology.

“…Methylene blue (MB) dye is a commonly used organic pollutant, which has high stability and low biodegradability and is thus difficult to degrade [ 1 ]. Various strategies, such as membrane filtration [ 2 ], advanced oxidation process (AOPs) [ 3 ], photocatalysis [ 4 , 5 , 6 ], and adsorption [ 7 ] have been reported for the treatment of organic wastewater. Among them, adsorption and the heterogeneous Fenton-like method, an AOP based on the activation of H 2 O 2 by a solid catalyst, are gaining importance in dye wastewater decontamination in recent excellent reviews due to their advantages of simple operation, high removal efficiency, low operating cost, and good recycling performance [ 8 , 9 ].…”

Biomass-derived raw bamboo charcoal (BC), NaOH-impregnated bamboo charcoal (BC-I), and magnetic bamboo charcoal (BC-IM) were fabricated and used as bio-adsorbents and Fenton-like catalysts for methylene blue removal. Compared to the raw biochar, a simple NaOH impregnation process significantly optimized the crystal structure, pore size distribution, and surface functional groups and increase the specific surface area from 1.4 to 63.0 m2/g. Further magnetization of the BC-I sample not only enhanced the surface area to 84.7 m2/g, but also improved the recycling convenience due to the superparamagnetism. The maximum adsorption capacity of BC, BC-I, and BC-IM for methylene blue at 328 K was 135.13, 220.26 and 497.51 mg/g, respectively. The pseudo-first-order rate constants k at 308 K for BC, BC-I, and BC-IM catalytic degradation in the presence of H2O2 were 0.198, 0.351, and 1.542 h−1, respectively. A synergistic mechanism between adsorption and radical processes was proposed.
