How does activated carbon help our health?

From the structure of activated carbon, activated carbon is formed by pyrolysis of carbon-containing substances such as coal, wood and hard fruit shells at high temperature and under certain pressure. In this activation process, huge surface area and complex pore structure are formed, which makes it have good adsorption capacity and good chemical stability. Activated carbon is also called activated carbon black. In addition to carbon, activated carbon also contains two kinds of blends: one is chemical binding elements, mainly oxygen and hydrogen, which remain in carbon due to incomplete carbonization, or foreign non-carbon elements chemically combine with the surface of activated carbon during activation, so is it really useful to use activated carbon to fight formaldehyde? The answer is useful, but not very useful: activated carbon can indeed adsorb formaldehyde in the air, but if we rely solely on activated carbon, we are bound to face two problems.

Don't be cheated. 99% of the manufacturers provide the data measured in the laboratory, which is the most ideal and favorable environment for the test results. You can refer to the description of the detection space in the activated carbon detection reports of various manufacturers. Either it is not described, or activated carbon belongs to contact adsorption, that is to say, formaldehyde molecules are adsorbed when passing through activated carbon, because the molecular gap is larger than that of activated carbon. Unlike magnets, distance attracts. Therefore, indoor air flow is general, and activated carbon can absorb very little formaldehyde.

At present, the formaldehyde content in home decoration is basically high. For the sake of family health, people are afraid of formaldehyde. Various in addition to formaldehyde products are common in in addition to formaldehyde, and activated carbon is one of them. However, according to the reflection, it is actually a psychological comfort to adsorb formaldehyde with activated carbon.

Activated carbon is a kind of physical adsorption. Based on the principle that carbon can adsorb harmful gases with peculiar smell, it can adsorb macromolecular gas suspended particles in the air, but it can achieve the purpose of filtering and purifying the air. Activated carbon has been used for a long time and has the advantages of stability, non-toxicity and no side effects, and the cost is reasonable.
