VSN-33 is a convenient and cost-effective solution for removing arsenic from drinking water. The iron hydroxide-based media was designed to help reach the newest World Health Organization (WHO) requirement for arsenic: 10 parts per billion. VSN-33's high capacity makes it an ideal non-regenerable, single-use product.

The Phase I research will determine the capacity and rate of uptake of lead, cadmium, and arsenic species from juice and form the basis for scaling to pilot and commercial scale in Phase II (in collaboration with a juice processing company). The product will be extremely beneficial to juice processors, juice packers and juice blenders.

Arsenic is a semi-metallic element. Although it is rare to find pure arsenic in nature, inorganic arsenic compounds are found in complex minerals containing copper, lead, iron, nickel, cobalt, and other elements.

Arsenic is released into the air by volcanoes, through weathering of arsenic-containing minerals and ores, and by commercial or industrial processes. Arsenic occurs naturally in the earth's crust, and much of its dispersion in the environment stems from mining and commercial uses. In industry, arsenic is a byproduct of the smelting process ...

In the U.S., high concentrations of naturally occurring arsenic are more common in the West, Midwest, parts of Texas, and Northeast, but can occur almost anywhere. This map shows the probability of arsenic in private well water greater than 10 parts per billion (ppb), the federal maximum contaminant level for arsenic in public water supplies (New Hampshire and New Jersey have adopted 5 ppb as ...

Arsenic is naturally-occurring throughout the environment and also widely used as a preservative for treated wood and as a pesticide in fields where we grow our food.Because of its chemical nature, it is frequently bioavailable and easily absorbed. Accurate and precise measurements of this classified human carcinogen are critical for managing our environment and protecting human health and safety.

Arsenic in Gold Processing: Mineral Processing and Apr 26, 2007The processing of gold bearing sulphide minerals which contain arsenopyrite and other complex arsenic sulphide minerals results in arsenic containing emissions and effluents which must be given careful consideration in relation to clean air and clean water standards.

Arsenic (As) is found in waters such as seawater, warm springs, groundwater, rivers, and lakes. In aquatic environments, As occurs as a mixture of arsenate and arsenite, with arsenate usually ...

At least seven commercially available adsorptive media are actively marketed nationwide for arsenic removal from drinking water. Most are iron-based oxides but titanium- …

Jul 22, 2017· Environmental aspects of processing these ores associated with arsenic or other toxic metals need to be carefully considered. The U.S. Bureau of Mines investigated an alkaline oxidative leaching procedure for treating gold-bearing arsenopyrite (FeAsS) ore, as one of the continuing efforts to develop efficient and environmentally safe ...

Arsenic and arsenic compounds have been produced and used commercially for centuries. Current and historical uses of arsenic include pharmaceuticals, wood preservatives, agricultural chemicals, and applications in the mining, metallurgical, glass-making, and semiconductor industries. Arsenic was used in some medicinal applications until the 1970s.

[2] Arsenic is rarely found as a pure metal, but is often a component in sulfur-containing minerals, the most common of which is arsenopyrite. [2] Commercially, arsenic is produced as arsenic xide or as a pure metal. [3] However, these have not been produced in the United States since 1985.

Ores contaminated with arsenic can liberate arsine when treated with acid. 1 Arsine is commercially produced for use in organic synthesis, and the processing of solid state electronic components. In industrial settings arsine poisoning generally results from the accidental formation of arsine gas.
