Can bamboo charcoal absorb formaldehyde?

After moving into a new home, you should move in immediately, but many people dare not move in. Although the materials used for decoration now do not contain formaldehyde, perhaps because there are special groups in the home, such as children, pregnant women and babies, most people are still taboo about this issue and want to clean up the formaldehyde quickly. Then, whether bamboo charcoal can absorb formaldehyde has become a concern for many people.

Can bamboo charcoal absorb formaldehyde?

Of course bamboo charcoal can absorb formaldehyde! However, the ability to absorb does not mean that bamboo charcoal can remove formaldehyde, because bamboo charcoal can not only absorb formaldehyde but also release formaldehyde to cause secondary pollution! Are you shocked after seeing this? Do you have the urge to throw away all the bamboo charcoal in your home? Don't be impulsive, the truth is not that bad.

Experiment on bamboo charcoal absorption of formaldehyde

Experimental Preparation

Put the bamboo charcoal into a U-shaped tube, connect the air inlet at one end to the formaldehyde pollutant, and the air outlet at the other end to the detector to monitor the formaldehyde concentration in real time.

Experimental Description

When the formaldehyde concentrations at both ends are the same, the bamboo charcoal in the U-shaped tube has reached a saturated state of adsorbing formaldehyde.

Experimental procedures

After six hours of testing, it was found that the concentration of formaldehyde adsorbed by bamboo charcoal reached saturation

Experimental Results

Bamboo charcoal absorbs formaldehyde. At 25 degrees Celsius, the adsorption capacity of bamboo charcoal is about 909 mg of formaldehyde per 100g of bamboo charcoal.

Experiment on bamboo charcoal absorbing formaldehyde and then releasing it

Experimental Preparation

Prepare a 30-liter container with zero formaldehyde, put the formaldehyde-absorbing bamboo charcoal into the container, seal it and place it in a sealed container.

Experimental procedures

After calculation and testing, it was found that the formaldehyde concentration in the container was 0.03 mg

Experimental Results

From the above experiments, we know that bamboo charcoal absorbs formaldehyde and will release formaldehyde again.

Experts explain: "This is a dynamic balance. When the concentration and temperature are determined, adsorption and desorption reach a balance." That is to say, when bamboo charcoal has reached saturation in adsorbing formaldehyde and is placed in an environment without formaldehyde, the original balance will be broken and the previously adsorbed formaldehyde will naturally be released.
