اقرأ أكثرThe environmental mobility of antimony (Sb) is controlled by interactions with iron (Fe) oxides, such as ferrihydrite. Under near-neutral pH conditions, Fe(II) catalyzes the transformation of ferrihydrite to more stable phases, thereby potentially altering the partitioning and speciation of associated Sb. Although largely unexplored, Sb itself may …

اقرأ أكثرAntimony is commonly listed as a critical mineral, particularly in the United States and European Union [1]. Its criticality, or supply risk, is derived from a combination of economic vulnerability, disruption potential of supply, and trade exposure [2].Disruption potential relates a country's ability and willingness to supply a commodity.

اقرأ أكثرMetal mining and pharmaceutical manufacturing are the primary sources of the toxic form of Sb [(Sb(V)] (Zhuang et al., 2018).Similarly, sewage sludge, emissions from the vehicle, leaching from plastic waste, industrial dumps, and direct infiltration from solid wastes are also important sources of Sb in the environment (Chu et al., 2021; Hu et al., …
اقرأ أكثرResearchers are increasingly concerned about antimony (Sb) in ecosystems and the environment. Sb primarily enters the environment through anthropogenic (urbanization, industries, coal mining, cars, and biosolid wastes) and geological (natural and chemical weathering of parent material, leaching, and wet deposition) processes.
