BEHAVIOR OF ANTIMONY AND ARSENIC IN SULFURIC ACID .
Recently, arsenic and antimony contents tend to increase in a conventional electrolyte for the electrorefining of copper. The elements form often a floating slime which lowers the quality of electrolytic copper(4). To clarify the behavior of antimony and arsenic in sulfuric acid solution for ...

Arsenic and Antimony Sulphide Minerals in Cyanidation
· The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even are low and the solutions soon become 'foul.' The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.

Like arsenic, dissolved antimony is primarily in the pentavalent oxidation state. Antimony (III) and methyl Sb, primarily monomethyl (MMSb), are found in surface waters, but dimethyl and trimethyl antimony also have been detected [Ellwood and Maher, 2002]. Benson and Cooney [1988] reported the production of a methylated antimony lipid by a

· Arsenic, antimony, and lead concentrations from ten radiometricallydated sediment cores are used to assess if: 1) there is evidence of deposition of arsenic, antimony, and lead from Giant and Con mines dispersing beyond the previously determined 30 km radius; 2) spatiotemporal patterns, degree of enrichment, and excess inventories for arsenic and antimony differ with respect to wind direction ...
Removal of Toxic Arsenic and Antimony from Groundwater ...
The source water was groundwater in abandoned silver mine, naturally contaminated by 6080 ppb of arsenic and antimony below 10 ppb. This water represents one of the sources of drinking water for Park City and constitutes about 44% of the water supply.
Arsenic
Arsenic, atomic number 33 lies in between phosphorus and antimony in group 15, the so called Nitrogen group of the periodic table. Members of the group including of course nitrogen, along with arsenic, phosphorous, antimony and bismuth are particularly stable in compounds because they tend to form double or triple covalent bonds.
Antimony
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental is a has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.. The primary use of arsenic is in alloys of lead (for example, in car ...
Influence of Soil Phosphate on the Accumulation and ...
· Fertilizers containing phosphate (PO 4 3−) are commonly used within the agricultural industry and are known to increase the bioavailability and mobility of metalloids like arsenic (As).This may increase plant uptake of As and hence pose a risk to human health. Arsenic and antimony (Sb) often cooccur in contaminated soils; however, little is known about the interactions between As and .

of arsenic and antimony Water quality — Determination
Antimony concentrations in natural waters are generally well below 10 μg/l. Arsenic and antimony occur naturally in organic and inorganic compounds and may have oxidation states −III, 0, III and V. In order to fully decompose all of the arsenic or antimony compounds, a digestion procedure is necessary.
Arsenic, antimony, and germanium biogeochemistry in the ...
Arsenic and antimony concentrations are lower than in the open oceans and in most rivers. In the oxic waters, the pentavalent species of As and Sb predominate, while in the anoxic basins, the distribution shifts to the trivalent species and possibly some sulfocomplexes.
Antimony in Drinkingwater
The chemical behaviour of antimony is as complex as that of arsenic, its neighbour in the periodic table (Wiberg, 1985). It is speculated that antimony could be a natural cocontaminant with arsenic in some drinkingwaters (Gebel, 1999b). Soluble forms of antimony (and arsenic) tend to be quite mobile in water, whereas less soluble species
