Problems solved by technology

Another researcher impregnated microporous granular carbon in phosphoric acid solution, soaked activated carbon in ZnCl 2 In the solution, the formaldehyde in the indoor air is adsorbed by the dried activated carbon, but the adsorption of formaldehyde by activated carbon is easy to reach saturation
Other studies have found that photocatalysts have a good degradation effect on air pollutants, but this method requires ultraviolet light and professional operation

Abstract

The invention relates to the field of odor removal, in particular to an environmental-friendly odor-removing formaldehyde composition and a preparation method thereof. The composition at least comprises the following raw materials in parts by weight: 10-30 parts of sepiolite, 1-8 parts of a surfactant, 0.1-0.5 part of a carbohydrazide modified graphene oxide-nano titanium dioxide compound, 1-3 parts of plant essential oil and 50-80 parts of deionized water. The preparation method of the environmental-friendly odor-removing formaldehyde composition at least comprises the following steps: uniformly mixing the sepiolite, the surfactant and the deionized water so as to obtain a mixed solution, further putting the carbohydrazide modified graphene oxide-nano titanium dioxide compound into the mixed solution, heating to be less than 50 DEG C, stirring to react for 1 hour, further adding the plant essential oil, uniformly stirring, and leaving to stand for 24 hours at 0 DEG C, so as to obtain the environmental-friendly odor-removing formaldehyde composition.

Description

technical field [0001] The invention relates to the field of deodorization, in particular, the invention relates to an environment-friendly deodorant formaldehyde-removing composition and a preparation method thereof. Background technique [0002] In people's daily life, formaldehyde contained in consumer goods such as interior decoration materials, furniture, and specially arranged clothing fabrics has become one of the serious pollutants in indoor air. [0003] Researchers have found that the hanging foliage plant Chlorophytum can purify formaldehyde in indoor air, but the plant adsorption method takes a long time to remove formaldehyde and the adsorption capacity is limited. Another researcher impregnated microporous granular carbon in phosphoric acid solution, soaked activated carbon in ZnCl 2 In the solution, the formaldehyde in the indoor air is adsorbed by the dried activated carbon, but the adsorption of formaldehyde by activated carbon is easy to reach a saturated ...
