1. The mechanism of UV sterilization?
UV can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure of microorganisms, so that bacteria die or can not reproduce, so as to achieve the purpose of sterilization.
2. UV sterilization band?
According to the international ultraviolet society, "the ultraviolet spectrum (the 'germicidal' region) that is very important for water and air disinfection is the range absorbed by DNA (RNA in some viruses). This band is about 200-300 nm.
It is known that the bactericidal wavelength extends to more than 280 nm, and now it is generally considered to extend to 300 nm. However, this may change with more research. Scientists have shown that ultraviolet light with wavelengths between 280nm and 300nm can also be used to kill bacteria.
3. The most suitable wavelength for sterilization?
There is a misunderstanding that 254 nm is the best wavelength for sterilization, because the peak wavelength of low-pressure mercury lamp (only determined by the physics of the lamp) is 253.7 nm. In fact, as mentioned above, a certain range of wavelengths have bactericidal effect. However, the wavelength of 265 nm is generally considered to be the best because it is the peak of DNA absorption curve. Therefore, UVC is the most suitable band for sterilization.
