I was on the phone the other day speaking with a potential customer. He had found Selective Micro through a Google search of water disinfectants and treatment chemicals and decided to give us a call. Chlorine dioxide was a little new to him so he was very curious to learn about our products.
As we were discussing our products and the molecule, he asked me, “Zach, what makes this chlorine dioxide stuff any better than chlorine or hydrogen peroxide or the next chemical?”
It’s a common question that we’re asked almost daily, so I thought it might be a good idea to write a blog that explains some of the biggest advantages of chlorine dioxide.
When it comes to disinfectants, chlorine dioxide ranks in the top in terms of effectiveness. The secret to its power is the number of electrons that it is able to take away from pathogens and organisms. The ClO₂ molecule has the ability to steal, or accept, 5 electrons. Therefore, chlorine dioxide has an oxidation capacity of 5e-. When you compare that number to other chemicals, it becomes clear that chlorine dioxide is able to “deactivate” more pathogens.
- Ozone: 2e-
- Hydrogen Peroxide: 2e-
- Sodium Hypochlorite: 2e-
- Hypochlorous Acid: 2e-
- Chlorine dioxide: 5e-
Before this oxidation process takes place, chlorine dioxide must choose what materials it wants to react with. However, unlike most oxidizers, it is a little picky! This is known as oxidation potential, or reduction potential, and it is the tendency of a molecule to accept electrons. The oxidation potential of chlorine dioxide is 0.95 volts. When compared to other chemicals (below) you can see the difference!
- Ozone: 2.07V
- Hydrogen Peroxide: 1.78V
- Sodium Hypochlorite: 1.49V
- Chlorine dioxide: 0.95V
As you can see, the ClO₂ molecule is much more selective. What this means is that instead of reacting with, for instance, the small, delicate pieces inside of a clinical analyzer, it reacts with the organic materials and pathogens inside of the machine. Because of this, chlorine dioxide can be much more effective at a much lower concentration because electrons are not wasted.
Ease of Use
Chlorine dioxide can be a very easy chemical to use and create. Most companies give you a pack of chemicals and an attendant volume of water. This allows you to know exactly how much ClO₂ you are generating. Selective Micro Technologies makes it even easier with our patented “micro-reactors”.
These micro-reactors, not dissimilar from tea bags, contain the precursor chemicals required for chlorine dioxide. Further still, most micro-reactors come in a pouch that holds exactly the amount of water you need to generate the concentrate. That means no measuring and no handling of chemicals. All you do is simply add water then spray the surface you want to disinfect.
Although I only discussed three, there certainly are more advantages we could discuss! If you would like to know more, get in touch with me at firstname.lastname@example.org.
