Antimony is detected in soil and water with elevated concentration due to a variety of industrial applications and mining activities. Though antimony is classified as a pollutant of priority interest by the United States Environmental Protection Agency (USEPA) and Europe Union (EU), very little is known about its environmental behavior and adsorption mechanism.
Antimony has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores stibnite (Sb 2 S 3) and valentinite (Sb 2 O 3).Nicolas Lémery, a French chemist, was the first person to scientifically study antimony and its compounds.
Antimony - Antimony - Properties and reactions: The most stable form of elemental antimony is a brittle, silvery solid of high metallic lustre. Electrolytic deposition of antimony under certain conditions produces an unstable, amorphous form called "explosive antimony," because, when bent or scratched, it will change in a mildly explosive manner to the more stable, metallic form.

Jul 01, 2019· Our method electrolyzes the water molecules into H+ and OH- ions. This process draws out potentially harmful elements like aluminum, antimony, arsenic, barium, cadmium, lead, silver and uranium. The hydrogen ions positively charge the water and draw out the negatively charged ions of the toxins, binding any heavy metals like a magnet.
