Abstract. A novel interrupted gas flow (IF) technique has been proposed for highly sensitive determination of ultratrace levels of arsenic and antimony in water Arsenic and antimony: Sources and toxicity. Arsenic (As) and antimony (Sb) are trace elements with metalloid properties, showing a wide distribution in the environment (Kabata-Pendias & Mukherjee, 2007 Full article: Stabilization and encapsulation of
Arsenic content in copper concentrates is continuously increasing worldwide. It is desirable to remove arsenic from copper in the earlier stages of copper making due to the deposition of arsenic to The main body of the discharge chamber was constructed following the design given by Marcus et al. [26], but in our experiments, the gas entries at the main body of the chamber were not used (the plasma gas was introduced either through the limiting disc or through the hollow cathode).The limiting disc used for these purposes was a disc Arsenic and antimony determination by on-line flow hydride
Coexisting arsenic (As) and antimony (Sb) in mining wastewater is a common and great concern. On-site simultaneous removal of As and Sb from mining wastewater was achieved by using a reusable granular TiO 2 column in this study. To evaluate the accuracy of the scale-up procedure, As and Sb adsorption from wastewater Arsenic is a natural component of the earth’s crust and is widely distributed throughout the environment in the air, water and land. It is highly toxic in its inorganic form. People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food cropsArsenic World Health Organization (WHO)
The average leaching efficiencies of arsenic, antimony, cadmium, indium, lead and zinc were 95.6%, 5.0%, 0.03%, 2.3%, 4.4% and 31.8%, respectively. The discharge of solid wastes is strictly regulated in China, and the identification standards for hazardous waste—Identification for extraction toxicityThe century-old mining development and utilization of antimony (Sb) ore in Xikuangshan (XKS) mine, groundwater antimony pollution has attracted great attention. At present, the sources and geochemical behaviors of high Sb groundwater in this area have been widely recognized, but morphological distribution and formation mechanisms of Morphological Distribution and Formation Mechanisms of Antimony
all arsenic compounds are highly toxic protoplasts. Many countries in the world are seriously affected by arsenic pollution. Arbitrary discharge of arsenic-containing non-wastewater will cause serious harm to human’s health and environmental balance. Arsenic can hinder the normal metabolism of cells and cause cell death.Arsenic, antimony, chromium, and (underestimated) thallium attract the closest attention of toxicologists and analysts. The properties of those elements depend on the oxidation state in which they occur. (VI), whose percentage in the heated water discharge zone and dam zone was 75% and 62%, respectively. In the study,the authors Arsenic, Antimony, Chromium, and Thallium Speciation in
Arsenic (As) and antimony (Sb) concentrations in water and sediments were determined along flow paths in the Sarouq River, Zarshuran and Agh Darreh streams. The results indicate high As and Sb concentrations in water and sediment samples. Raman spectroscopy shows hematite (α-Fe 2 O 3), goethite [α-FeO(OH)] and lepidocrocite [γ Continuous flow hydride generation for the preconcentration and determination of arsenic and antimony by GFAAS.

A lot of anthropogenic activities can discharge arsenic into the ecosystem such as industrial wastes, incineration of municipal, pesticide production and wood preserving. In addition, most arsenic soluble species can enter surface waters via runoff and leach into the groundwater. Around forty million people from all over the world are A high-efficient liquid spray dielectric barrier discharge (LSDBD) plasma induced vapor generation technique is developed for the simultaneous determination of selenium, silver, antimony, leadZhenli ZHU Professor (Full) PhD China
The conditions of instrumentation and vapor generation of arsenic, antimony, bismuth and mercury were optimized. The optimized concentrations of KBH 4 and HCl required for analytes generation were 1.3% (m/v) and 20% (v/v), respectively. The interferences of coexisting ions and mutual hydride interferences were investigated The cylindrical configuration of the DBD atomizer cell has been described previously [31].Two major parts are included in the DBD atomizer cell: the inner tube (4 mm i.d × 5 mm o.d × 35 mm length) acted as the discharge reactor, and the outer tube (10 mm i.d × 11 mm o.d × 40 mm length) was used for keeping the stable Ar gas flow without the Simultaneous determination of arsenic and antimony by
1 Introduction. Arsenic (As) and antimony (Sb) are toxic and carcinogenic metalloids that are common co-contaminants in aquatic environments impacted by mining activities (Arsic et al., 2018; Ashley et al., 2007; Fawcett et al., 2015; Johnston et al., 2020; Tighe et al., 2005).The aquatic behavior of As and Sb is a subject of considerable Aqueous arsenic and antimonyThe discharge source water pH is ∼6.85–7.00, with the lowest pH occurring in the hottest springs (approaching local boiling). At 85 °C, neutral pH is ∼6.2, and the standard state (25 °C) equivalent pH of ETGF spring water is ∼7.2 (calculated using PhreeqC). Slightly higher pH waters are found in the Partitioning geochemistry of arsenic and antimony, El Tatio
Antimony and arsenic pollution occurrences have become more frequent as a result of the progressive increase in the usage of antimony (Sb) and arsenic (As) in many nations worldwide in recent decades With the discharge of industrial effluent or the erosive action of rains, chemicals such as Sb and As created during combustion or 土壤锑、砷污染风险评估与富集植物筛选——以湖南某锑矿山为例 [J]. 现代矿业, 2018, 34 (8):216-221.

It is well-known that the mining industry in Chile and the world is searching for eco-friendly, highly efficient mineral treatments. This is because the content of toxic elements such as arsenic, antimony, and bismuth have increased in the copper concentrates in the last years. This trend has affected the market of this metal, as well as increased Determination of arsenic and antimony by atmospheric pressure glow discharge portable emission spectrometer with solid acid hydride generation.
