The best thing to absorb formaldehyde

Formaldehyde is a toxic substance. It often appears in some chemical raw materials and in some furniture during decoration. It is particularly harmful to human health. For a newly renovated house, do not move in immediately. You should adopt some better methods to absorb and remove formaldehyde. For example, bamboo charcoal is a better method to absorb formaldehyde. Frequent ventilation is also important.

The best thing to absorb formaldehyde

Bamboo charcoal adsorption method: Bamboo charcoal is recognized as an expert in absorbing drugs, and it is used in activated carbon masks and gas masks. The adsorption capacity of bamboo charcoal is 2-3 times stronger than that of ordinary charcoal. Due to its low price, it is also a commonly used material for removing decoration pollution in citizens' homes. Bamboo charcoal actually adsorbs formaldehyde rather than absorbs it. Due to the fragility of this adsorption, when the adsorption reaches the saturation value, formaldehyde may be released again. She reminded that the charcoal bag can be placed in the sun for two or three days before being used again.

Photocatalyst technology: It works quickly in rooms with high concentration of formaldehyde. Its working principle is to catalyze the oxidation-reduction reaction of harmful substances such as formaldehyde, benzene, VOC, etc. under ultraviolet light, and produce carbon dioxide, water and other substances that are harmless to the human body. Guo Jingzhuo introduced that this method may cause secondary pollution. For example, some furniture surfaces are painted and have yellowing resistance requirements. New harmful substances may be produced under the photocatalytic redox reaction.

Ozone meter: produces ozone in the air and water, causing redox reactions. It should be noted that since ozone is harmful to the human body, you can turn on the ozone meter, close the door, and after more than ten minutes, enter the room to ventilate and open the windows to reduce the impact on the human body.

Negative ion generator: can decompose harmful substances such as formaldehyde through high-voltage ionization without any dead corners.

Emergency response and first aid

1. Quickly evacuate personnel to upwind areas, isolate until the gas is completely dispersed, and cut off the fire source. If fire occurs, use foam, carbon dioxide or sand to extinguish the fire.

2. Proper ventilation, mixed with sand or other non-combustible adsorbents for absorption (if sprayed water can only reduce evaporation, it cannot reduce its flammability), and then transport to the waste disposal site. If a large-scale leak occurs, build a dike to collect the waste, and then transfer it for recycling or harmless treatment.

3. Deal with poisoned persons. Quickly evacuate people to fresh air, keep them quiet and warm, and give them oxygen if necessary. Pay attention to observe early changes in the condition. The poisoned person should avoid activities, and those who have upper respiratory tract irritation reactions should be observed for at least 24 hours. In case of eye contact, rinse with plenty of water for several minutes and then seek medical attention. In case of skin contact, take off contaminated clothes and rinse with plenty of water or shower. Those with serious conditions should be sent to hospital for emergency treatment.
