Questions about UVC LED and COVID-19
Question 1: What is the difference between a blacklight and a bluelight?
A "blacklight" is a fluorescent light tube that emits at about 365 nm - this is just below the wavelengths that humans can see, but it is absorbed by most pigments in clothes so that they "fluorescence". This is the effect seen in many bars and discos.
I'm not sure what you mean by a "bluelight" - perhaps you means "germicidal" low-pressure mercury lamp. They do glow "blue", but most of their output is at 254 nm, so DO NOT look directly at such a lamp when it is operating. These lamps are used in air and water disinfection, since the 254 nm light is absorbed by DNA in bacteria and viruses causing their inactivation.
Question 2: I am familiar with the Fenton's Reagent (hydrogen peroxide + iron salts at pH ~4 to destroy phenol in wastewaters. Why I do not see any data or publications on the use of Fenton's Reagent as an antimicrobial? The hydroxyl radical is so strong; it should kill microbes.
Yes, Fenton's reagent would be very effective as an antimicrobial treatment of wastewater. The antimicrobial effect would probably arise more from the low pH (Fenton's works best at a pH of about 3) than from the generation of ·OH radicals.
It is more a question of economics. Lowering the pH to 3-4 is very costly and increases the dissolved solids level of the water. I think that you would find that UV disinfection would be a much cheaper process that Fenton's treatment.
