Introduction of arsenic trioxide?


  Every kind of thing has its own value, and in our daily life, there are many things and products that cannot be separated. So in the industrial field, there are also a lot of machinery and equipment in different areas to play their role, arsenic trioxide is no exception, today we will talk about arsenic trioxide are used in what areas? If you are interested, continue to look down together.

  Arsenic trioxide is an odorless, white powder or crystal. There are three crystalline forms: monoclinic crystal relative density of 4.15, 193 ℃ sublimation; cubic crystal relative density of 3.865; amorphous relative density of 3.738, melting point of 312.3 ℃. Slightly soluble in water to produce subkunic acid. Monoclinic and cubic crystals are soluble in ethanol, acids and bases; amorphous body is soluble in acids and bases, but insoluble in ethanol. Industrial products are slightly red, gray or yellow depending on impurities.

  Arsenic trioxide is mainly used to extract elemental arsenic. It is the raw material for smelting arsenic alloy and manufacturing semiconductors. It is used as a clarifier and decolorizer in the glass industry to enhance the light transmission of glass products. In agriculture, it is used as a disinfectant and rust remover for pest control, and as a raw material for other arsenic-containing pesticides. Used in the manufacture of paints and dyes. Arsenic trioxide is used as a chemical reagent. It is also used in gas desulfurization, wood anticorrosion, boiler anti-scaling, ceramics and enamel. Used as analytical reagent, such as reference reagent, reducing agent. Chlorine absorber. Also used in the preparation of subquinate, as a preservative. Used in glass, enamel, pigment industry and leather preservative, etc.

  For the treatment of arsenic trioxide spill, it is mainly necessary to isolate the contaminated area of the spill and restrict access. It is recommended that emergency personnel wear self-contained positive pressure respirators and protective clothing. Do not come into direct contact with the spill of arsenic trioxide. Small spills: Avoid raising dust and collect it in a dry, clean, covered container with a clean shovel. Large spills: Cover with plastic sheeting or canvas to reduce scattering. Then collect, recycle or transport to a waste disposal site for disposal.
