Synergistic effects of Fe-Mn binary oxide for gaseous arsenic removal in flue gas

Gaseous Arsenic Capture in Flue Gas by CuCl2-Modified Halloysite Nanotube Composites with High-Temperature NOx and SOx Resistance

“…The experiment contained three parts (Figure S1): an arsenic adsorption part, a digestion part, and a detection part. 7 The arsenic adsorption part mainly consisted of SFG generation (10 vol % O 2 , 10 vol % CO 2 , 800 ppm SO 2 , 300 ppm NO, 8 vol % H 2 O, and N 2 ), As 2 O 3 generation, and As 2 O 3 adsorption. The detailed experiment setup is described in Supporting Information.…”

“…Arsenic and its compounds are recognized as the most potent carcinogens to human beings. − Up to 550 tons of arsenic per year were reported to be emitted through flue gas from coal-fired plants in China, which are regarded as one of the major arsenic anthropogenic emission sources . Unlike other metals, the toxicity of arsenic depends not only on its total quantity but also on its existing species. ,, Trivalent arsenic [As­(III)] is 50 times more toxic than pentavalent arsenic [As­(V)] . Unfortunately, most of the arsenic released through flue gas from power plants has been identified as As 2 O 3 [As­(III)].…”

A computational study on the adsorption of arsenic pollutants on graphene-based single-atom iron adsorbents

“…25,26 As described in previous studies, arsenic pollutants in flue gases are adsorbed on the surface of adsorbents first and then the arsenic oxidation occurs at activated sites. 27,28 The initial adsorption of arsenic species on adsorbents is a fundamental step to induce the catalytic oxidation of arsenic. In addition to acting as the adsorbent, SACs can also be used directly as the catalysts for subsequent dearsenicization reactions.…”

Environmental Management Zoning of Coal-Fired Power Plants in China in the Context of Carbon Neutrality

“…However, with the accelerating process of industrialization and the rapid development of the economy, the unreasonable development and use of coal and other natural resources for energy, and the arbitrary emission of CO2, SO2, NOx and other pollutants, make the world face severe challenges of resource depletion, the deterioration of the ecological environment, global warming and imbalance of social and economic development [5][6][7]. Among these severe challenges, gaseous pollutants from coal-fired power and coal-fired processes are one of the main sources of air pollution in China [8][9]. In order to solve these problems, the coordinated development of resources, environment and social economy has attracted the world's attention [10][11].…”
