Combining the data in the table 2 and the table 3 and combining the examples 1 to 11, the formaldehyde removing spray prepared by the method can not only rapidly remove high-concentration formaldehyde, but also rapidly reduce the formaldehyde content of low-concentration formaldehyde to 0.1mg/m 3 The requirements of national standards on indoor living environment can be met.
As can be seen by comparing example 3 with comparative example 1 and combining the data in tables 2 and 3, when the amount of carboxymethyl chitosan exceeds 2%, the aldehyde removing efficiency of the aldehyde removing spray decreases for both high and low concentrations of formaldehyde. The reasons may be that excessive carboxymethyl chitosan may affect the atomization effect of the aldehyde-removing spray, which results in poor dispersibility of the aldehyde-removing spray, and the efficiency of the water-soluble adsorption matrix for adsorbing formaldehyde is reduced, which results in a reduction in the decomposition rate of carbohydrazide, vinylurea and urea on formaldehyde.
Comparing example 3 with comparative examples 2 to 4 and combining the data in tables 2 and 3, it can be seen that when the single carbohydrazide, ethylene urea or urea is used instead of the combination of carbohydrazide, ethylene urea and urea, the aldehyde removing efficiency of the aldehyde removing spray is reduced, and the aldehyde removing spray can not be used for removing aldehyde within 30min to reach a concentration range of 0.5mg/m 3 The low concentration formaldehyde on the left and right is reduced to 0.1mg/m 3 The following.
As can be seen by comparing example 3 with comparative example 5 and by combining the data in tables 2 and 3, when taurine was replaced with an equal amount of deionized water, the aldehyde removing spray had a greatly reduced aldehyde removing efficiency for high concentration formaldehyde, and at the same time, the aldehyde removing spray did not substantially work for low concentration formaldehyde.
Comparative example 3 andas can be seen from examples 6 and 7 in combination with the data in table 2, when taurine is used as the organic acid, the aldehyde removal rate after 1 hour is 90.8%, and the aldehyde removal rate after 8 hours is 99.5%; when the organic acid adopts acetic acid, the aldehyde removing rate after 1h of the aldehyde removing spray is 89.5%, the aldehyde removing rate after 8h is 91.2%, when the organic acid adopts citric acid, the aldehyde removing rate after 1h of the aldehyde removing spray is 89.8%, and the aldehyde removing rate after 8h is 91.9%. In addition, the data in table 3 show that when taurine is used as the organic acid, the formaldehyde concentration of the formaldehyde can be reduced to 0.1mg/m within 15min when the formaldehyde removing spray is used for treating low-concentration formaldehyde 3 The following. Namely, when the organic acid in the formaldehyde removing spray adopts taurine, the formaldehyde removing efficiency of the formaldehyde removing spray to low-concentration formaldehyde is improved.
