The formaldehyde absorbing material of the present invention has formaldehyde eliminating capacity with active carbon as reference. Two test boxes were used for simultaneous comparison, one "U" tube was filled with 500 g of the formaldehyde absorbing material of the present invention, and the other was filled with 500 g of food grade activated carbon for adsorbing formaldehyde, and a formaldehyde meter (PPM Formaldehydemeter400, resolution 0.01PPM) was connected to the detector interface to measure the change in formaldehyde concentration in the box. The test box is sealed, then air containing 1.0ppm of formaldehyde is continuously sent into the box through the air inlet, and the air containing formaldehyde is supplemented into the box as soon as the concentration of the formaldehyde in the box is reduced. Finally, when the concentration of formaldehyde in the cartridge did not decrease any more within 30 minutes, the total amount of air volume input into the cartridge was recorded, the total amount of formaldehyde absorbed was calculated, and the total amount of formaldehyde absorbed was divided by the mass of the total absorbent (500 g for activated carbon and 500 g for formaldehyde absorbent of the present invention), and the ability of activated carbon and formaldehyde absorbent of the present invention to remove formaldehyde from air was calculated as shown in table 1 below, respectively.
TABLE 1 comparison of Formaldehyde absorption in air data
| Number of tests | Activated carbon (mg/g) | Formaldehyde absorbing material (mg/g) of the |
| 1 | 0.51 | 264.15 |
| 2 | 1.12 | 320.21 |
| 3 | 0.73 | 234.53 |
As can be seen from table 1, the formaldehyde absorbing material of the present invention has an absorption capacity 285 times or more the adsorption capacity of activated carbon.
Example 3
10 grams of the formaldehyde absorbing material formulated in example 1 was used. The dosage of the activated carbon is 2.85 kg calculated according to the formaldehyde absorption capacity of 285 times of that of the activated carbon. The formaldehyde absorption capacity was quantified by using the change in the formaldehyde concentration, and the test was carried out using a completely sealed stainless steel box (1.0. times.1.0 m) as the measurement space for formaldehyde. One box was filled with 10 g of the formaldehyde absorbent material prepared in example 2, and the other box was filled with 2.85 kg of activated carbon. The initial formaldehyde concentration was 2ppm, the room temperature was controlled at 25 ℃, the content of formaldehyde in the air in the box was monitored by constant sampling, and the average of three experiments was taken to obtain the concentration data shown in table 2 below.
Table 2 concentration data
| Time (hours) | Activated carbon | The formaldehyde absorbing material of the invention |
| 0 | 2.00 | 2.00 |
| 1 | 1.13 | 0.26 |
| 2 | 1.02 | 0.12 |
| 3 | 0.58 | 0.05 |
| 4 | 0.44 | 0.03 |
| 5 | 0.35 | 0.01 |

| 72 | 0.08 | Is lower than the detection limit |
| The air in the box is heated to 50 DEG C | 0.41 | Is lower than the detection limit |
The results in table 2 show that the formaldehyde absorbing material of the present invention has the action mechanism of absorption, can completely remove formaldehyde in air, and once absorbed, cannot release formaldehyde when heated. The activated carbon is only adsorbed, is balanced, cannot completely remove formaldehyde, and the adsorbed formaldehyde can be released again when the activated carbon is heated.
