Arsenic and Antimony – Comparison - Material Properties
Arsenic is a metalloid. Antimony Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. Source: Arsenic and Antimony – Applications Arsenic
Arsenic and antimony: comparative approach on mechanistic toxicology
A chemico-toxicological similarity between arsenic and antimony exists and their toxicology is often seen. Indeed, both elements possess several common properties, e.g. they are clastogenic but not mutagenic in the trivalent state and they have a carcinogenic potential: trivalent arsenicals are known to be human carcinogens and antimony(III) oxide (by …

Likewise, the level of residual total antimony in livers of infected mice 72 h after the end of treatment with Pentostam was not significantly altered between non–arsenic-exposed and arsenic-exposed groups (Table 1), suggesting that exposure to arsenic does not interfere with the accumulation of antimony in the infected tissues.

Assay Determination of Arsenic & Antimony
Determination of Arsenic and Antimony Together: Instead of separating arsenic from antimony in the hydrochloric-tartaric acid solution which was finally obtained, dilute the solution to four times its volume; pass sulphuretted hydrogen to saturation; filter the combined sulphides on a 4 cm. filter (weighed and dried in weigh-bottle at 110° C.); wash with water, …

1. Introduction. The first comprehensive study of the marine arsenic cycle occurred in the North Pacific Ocean over 27 years ago [Andreae, 1978], while investigations of its companion on the Periodic Table, antimony, began in earnest roughly 10 years later [e.g., Middelburg et al., 1988; Cutter and Cutter, 1995].The predominant form of arsenic, like …

The important role of native plant cover in terms of "stabilization" of these contaminants is demonstrated and the poor effectiveness of extraction procedures used for this type of soil assemblages, i.e., rich in specific mineral phases, is demonstrated. The soils are classified as Technosols with high contamination levels of As, Pb, and Sb.

The contaminated fields of Sb deposit cover an area over 70 km 2 (Ye et al., 2018). Mining activities have generated huge amount of waste dumps containing high concentrations of Sb and As.
Antimony - Wikipedia
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony xide, Sb 2 O 3.

In fact, the non-protein-bound, free trivalent arsenic is predominant in biological systems as the uncharged weak acid H 3 AsO 3 (p Ka =9.3) 28, 29, 30, and antimonite should be referred to as the uncharged Sb (OH) 3 [31]. However, the speciation of trivalent antimony in solution is not fully understood.

The production of arsenic usually occurs as a by-product of copper smelting, and is approximately in the range of 50,000–100,000 tons per year but this is a rough estimate based on previous global estimates by WHO ...
Assay Determination of Arsenic & Antimony
Arsenic will be precipitated as trisulphide. After 5 hours' standing, filter. Wash carefully with water, absolute alcohol and carbon disulphide, in succession. Finish the washing with alcohol. Dry at 110° C. Weigh on filter as trisulphide. Usually the trisulphide method is employed. For a check upon it, we use the pyro-arseniate method.

Arsenic - Wikipedia
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 crystal.Arsenic is a metalloid.It 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 …
