Background and overview of benzylarsonic acid


Arsenic is a necessary trace element for animal growth. When animals lack arsenic, their fertility status will be affected, and the yield and quality of meat, eggs and milk provided to human will be reduced, such as the decrease of amino acid absorption in poults, the decrease of conception rate in sows, and the decrease of milk production in goats. Organic arsenic, such as arsanilic acid, as an excellent arsenic-containing feed additive, is not only low in toxicity and easy to discharge, but also has almost no effect on meat quality and human health, and can promote the growth of meat livestock at the same time (weight gain), and also play the role of antibacterial (prevention of diarrhea and dysentery, etc.), antiparasitic, improve egg production rate and feed utilization rate, and improve the appearance quality of livestock products. In the 1950s, almost all large and medium-sized feed mills in the United States used organic arsenicals as feed additives. The azoarsine compounds in organic arsine (such as azoarsine-III) can be used as excellent indicators with good display effect and high sensitivity for zirconium, thorium and uranium plasma, and can detect low concentration of zirconium ions, which occupies a very important position in analytical chemistry. Organic arsenicals are also gaining attention in the field of pharmaceutical synthesis as a class of excellent antitumor drugs.

Benzylarsonic acid is used as a trapping agent in the flotation of cassiterite, wolframite and rare earth ore, and also as a trapping agent in the flotation of many kinds of metal oxide ores. It is the first effective trapping agent for wolframite and cassiterite fine mud in China.
