Who can tell me what are the advantages and disadvantages of activated carbon? Urgent. . .

Activated carbon belongs to physical adsorption, which can effectively eliminate part of formaldehyde, but it does not have the function of decomposing formaldehyde, so it needs to be aired regularly when used, otherwise it will be saturated and may bring secondary pollution. Formaldehyde can not be removed overnight, and its release life can be as long as more than ten years. Here are some in addition to formaldehyde methods for you to choose from.

First, Ruishi

It is a very popular purification product in the market in recent years, mainly because it has dual functions of absorption and decomposition, and can actively absorb free formaldehyde in the air without worrying about the influence of external factors such as temperature, humidity and light. The absorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body without air drying and secondary pollution. It should be noted that it is an irregular gray ore, not a round particle.

Second, activated carbon

Activated carbon is a traditional physical adsorption material, which is well received in indoor and outdoor pollution control. It has large specific surface area and strong adsorption capacity, but its adsorption capacity is limited and it does not have decomposition function. It needs to be replaced regularly when it is used, otherwise it may produce secondary pollution when it is saturated?

Third, open the window for ventilation

This is a gift from nature and the most economical and practical in addition to formaldehyde method. As long as the window is opened, fresh air will enter the room, diluting and purifying formaldehyde.

Fourthly, optical contact medium.

Photocatalyst, as its name implies, is a kind of catalyst mentioned in our junior high school chemistry. It decomposes formaldehyde into carbon dioxide and water by illumination, which reduces the indoor formaldehyde content and achieves the purpose of removing formaldehyde.

Verb (abbreviation for verb) high temperature

Under the condition of high temperature, it can promote the conversion of bound formaldehyde into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates into the interior of the board, although it can not be completely removed, its effect is still very obvious.

Formaldehyde is a high-grade toxic substance and a potential carcinogen. Before moving into a new house, in addition to formaldehyde is the top priority. According to the above, you can choose a variety of methods at the same time.
