“…The reasons may be due to the increase of H + that could improve the reaction efficiency between organic matter and reactive species. Simultaneously, it promoted the formation of highly reactive oxygen species, such as •OH, and facilitated the oxidation and decomposition of organic compounds [49]. In this study, RF can generate several reactive species that may assist in the decomposition and degradation of DOM in rainwater during treatment.…”

“…The protein-like component may have a large molecular weight that results in the incomplete dehydrogenation of aromatic rings [47,48]. A previous study demonstrated oxidation treatment using parallel electrodes during direct electrolysis treatment with the addition of chloride ion [49]. The results show that aromatic macromolecular organic compounds were degraded into small molecular substances, such as acetic acid and phenol.…”

Rainwater is a potential source of drinking water, but has various components of dissolved organic matter (DOM). DOM is a reservoir of potential hazards in drinking water. Therefore, a new method is required to purify rainwater as a drinking water source in terms of DOM aspects. A radio-frequency (RF) treatment system is introduced here to purify source water with a small possibility of contamination. RF is generated by applying a frequency of 1.5 MHz through a glass reactor with a diameter of 2 mm which is wrapped by a 2 mm copper wire. The results demonstrate that UV260 value and dissolved organic carbon (DOC) are reduced during RF treatment. DOC was reduced by a lower amount compared to UV260, suggesting the partial transformation of bio-refractory DOM. A fluorescence excitation-emission matrix showed that humic-like substances in rainwater were reduced faster than protein-like ones, indicating that humic-like substances are susceptible to reduction by RF treatment. The results offer information on the use of RF treatment in a rainwater purification process for the production of drinking water.

“…There are tar-rich coals with yields greater than 7%, and even high-tar coals containing 12% [ 8 , 9 ]. Although the coal in northern Shaanxi is of good quality and low sulfur content, the prepared blue carbon is of good quality and has a wide market, but the classification and utilization of tar is still an important problem that local coal enterprises urgently need to solve [ 10 , 11 , 12 ].…”

The quinoline-insoluble (QI) matter in coal tar and coal tar pitch is an important factor affecting the properties of subsequent carbon materials. In this paper, catalytic polycondensation was used to remove QI from heavy coal tar, and meso-carbon microbeads could be formed during the purification process. The results showed that AlCl3 had superior catalytic performance to CuCl2, and the content of QI and heavy components, including pitch, in the coal tar was lower after AlCl3 catalytic polycondensation. Under the condition of catalytic polycondensation (AlCl3 0.9 g, temperature 200 °C, and time 9 h), AlCl3 could reduce the QI content in heavy coal tar. The formed small particles could be filtered and removed, and good carbon materials could be obtained under the condition of catalytic polycondensation (AlCl3 0.9 g, temperature 260 °C, and time 3 h).

“… 13,14 Furthermore, the temperature window is wide, and V 2 O 5 (one of the SCR catalysts) is highly poisonous. 15–18 Therefore, it is necessary to develop a new catalyst with less pollution, low cost, and high efficiency. 19 Zhang et al 20 successfully synthesized a V 2 O 5 /Sn x Ti 1− x O 2 catalyst by means of impregnation.…”
