Mercury(II) Selenide CAS 20601-83-6 HgSe

Mercury Selenide is used as a photocatalyst to degrade organic dye pollutants, and the specific application steps are:

1. At room temperature (20-25°C), irradiated with visible light, using organic dye pollutants as substrates and HgSe as photocatalysts for photocatalytic degradation.
2. Activity evaluation of HgSe photocatalyst: The degradation rate of organic dye pollutants was measured, and its activity was measured by the time required for complete degradation.

In the application of the above-mentioned mercury selenide, the organic dye pollutants are rhodamine B or/and methyl orange. In the application of the above mercury selenide, the wavelength of the visible light is greater than 420 nm.

A new use of mercury selenide, a non-toxic and stable chemical substance used to replace mercury in high-pressure discharge lamps, using mercury selenide made of a compound of mercury and selenium to replace liquid mercury. The weight ratio of selenium is equal to the ratio of the gram molecular weight of the two elements. The dosage is to retain 0~50% of the liquid mercury in the high-pressure discharge lamp, and replace the rest of the mercury with mercury selenide of the corresponding gram molecular weight.

Metal halides, metals, and other chemicals can also be added to mercury selenide. The invention can greatly reduce the use of liquid mercury in high-intensity discharge lamps, and because HgSe is a stable substance, even if the lamp tube is broken, no liquid mercury or mercury vapor leaks, so mercury pollution can be greatly reduced.
