Transformation and migration mechanism of fluorine-containing pollutants in the pyrolysis process of spent lithium-ion battery.
Highlights Adsorption of electrodes to electrolyte can lead to fluorine-containing residues. Melting PVDF prevents the deep removal of fluorine-containing pollutants. A synergistic transformation mechanism of fluorine during pyrolysis is proposed. Abstract Pyrolysis is an effective method to remove organics (e.g. electrolytes and binders) from spent lithium-ion battery (LIB). In this study, the co-pyrolysis characteristics of […]

Increase in fluoride concentration in mine water in Shendong mining area, Northwest China: Insights from isotopic and geochemical signatures
Highlights The abundance and spatial distribution of F– in the mine water of the Shendong mining area were determined. The hydrogeochemical behaviours and formation mechanisms that further elevate F– levels in mine water during mining activities were evaluated. The hydrogeochemical processes of mine water at high F– concentration using stable isotopes (34SSO4, 18OSO4,18OH2O, and D) […]

Hydro-geochemical control of high arsenic and fluoride groundwater in arid and semi-arid areas: A case study of Tumochuan Plain, China
Highlights The enrichment of arsenic in groundwater is closely related to salt content of aquifer medium. Reduction environment caused by high organic matter content is key to arsenic enrichment. Alkaline environment has great influences on the enrichment of fluoride and arsenic compounds. Dissolution balance between carbonate minerals and fluorite controls the content of fluoride. Abstract […]
