Pure antimony does not change in air at room temperature, and it is not tarnished in humid air or pure water. If heated in air, the molten metal ignites. Above 750°C, steam oxidizes liquid antimony to antimony trioxide, and hydrogen is evolved.
Most emitted antimony is in the form of ATO, which is released as a result of coal burning or with fly ash when antimony-containing ores are smelted (Nriagu & Pacyna, 1988). Approximately 6400 tonnes of antimony are transported annually to oceans (Bowen, 1979). The chemical behaviour of antimony is as complex as that of arsenic, its neighbour in
1 Νοε 2021 · In this paper, we summarized the detection, analysis and removal methods of antimony, and introduced the environmental chemical behavior of antimony, including its occurrence form, fate and environmental harm effect, etc., to provide a reference for the study and treatment of antimony pollution.
1 Οκτ 2023 · High antimony levels in surface water (red), groundwater (yellow) and sediment (blue) are indicated by a series of different sizes of cycles which represent antimony concentration ranges of less than 5, 5–100, 100–1000, 1000–10000, and > 10000 μg/L (μg/g for sediment).
1 Οκτ 2023 · This paper focuses on the latest advances in research concerning antimony toxicity, identifies potential sources of antimony water pollution, and explores its migration pathways and biogeochemistry. Moreover, the study provides estimations of antimony quantities in different compartments.
CHAPTER 4. CHEMICAL AND PHYSICAL INFORMATION . 4.1 CHEMICAL IDENTITY Antimony (Sb) is in the fourth row of group 5A (IUPAC group 15) in the periodic table, residing between arsenic and bismuth. Antimony displays four oxidation states: -3, 0, +3, and +5. The most common and stable oxidation states of antimony in aqueous solutions and biological ...
The physical and chemical properties of antimony and selected antimony compounds are given in Table 4-2. Antimony metal is stable under ordinary conditions. Antimony is a poor conductor of heat and electricity (Li 2011). Antimony forms complex ions with organic and inorganic acids.
