In our study we focused on the geochemistry and mineralogy of Lake Orr and 25 Lake Whurr. While both lakes are poor in organic carbon (File Size: 1MB.

Chemical speciation is a very important subject in the environmental protection, toxicology, and chemical analytics due to the fact that toxicity, availability, and reactivity of trace elements depend on the chemical forms in which these elements occur. Research on low analyte levels, particularly in complex matrix samples, requires more and more advanced and sophisticated analytical methods Cited by: This paper describes the measurement of total antimony and antimony species in “real world” mine contaminated sediments using ICPMS and and high temperature microwave extraction procedures (90 °C and °C, respectively) using a range of nitric–hydrochloric acid combinations were examined as to their efficacy to extract antimony from six mine contaminated soils Cited by:

Elevated levels of arsenic (As) and antimony (Sb) in water and sediments are legacy residues found downstream from gold-mining activities at the Giant Mine in Yellowknife, Northwest Territories (NWT), Canada. To track the transport and fate of As and Sb, samples of mine-waste from the mill, and surface water, sediment, pore-water, and vegetation downstream of the mine were by: Distribution and Early Diagenesis of Antimony Species in Sediments and Porewaters of Freshwater Lakes Article in Environmental Science and Technology 37(6) April with Reads.

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl.

Metallic antimony was also known, but it was Pronunciation: UK: /ˈæntɪməni/, (AN-tə-mə-nee). The geochemistry of antimony is reviewed, and the use of the element as an indicator in geochemical prospecting for various types of mineral deposits is outlined. Antimony is widely diffused in many types of mineral deposits, particularly those containing sulphides and by: The chemical and mineralogical compositions of sediments and sedimentary rocks are extremely diverse.

Sediments may be classified according to the origin of the minerals composing the bulk sediment, with end-members being referred to as terrigenous, biogenic or metalliferous sediment.

Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony’s leading use is as a fire retardant in safety equipment and in household goods, such as mattresses.
