Embodiment

[0029] Embodiment: Deodorant effect demonstration

[0030] 1. Make 13 groups of compound chemical deodorants. And set deionized water as a blank control group, common chemical deodorant (manufacturer: Suzhou Senus Environmental Protection Technology Co., Ltd.; article number: Ecala) as a positive control group.

[0031] The specific formulations of each group of compound chemical deodorants are shown in Table 1. The figures in Table 1 refer to the mass fraction of this component in the formula, and the balance is water. In Table 1, polysorbate 80 is uniformly used as the nonionic surfactant, and potassium hydrogen persulfate complex salt is uniformly used as the potassium metal compound salt.

[0032] The formula comparison table of each group compound chemical deodorant of table 1

Abstract

The invention belongs to the field of deodorants, and particularly relates to a chemical deodorant and a preparation method thereof. According to the specific technical scheme, a novel composite polar molecule with a deodorization effect is provided, and a novel composite chemical deodorant is further provided. The chemical deodorant can efficiently treat stink, especially hydrogen sulfide and mercaptan stink, has small harm to the environment, and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the field of deodorants, and in particular relates to a chemical deodorant and a preparation method thereof. Background technique [0002] With the advancement of urban-rural integration and industrialization, while people's lives are improving day by day, the emission of industrial waste gas and the large amount of malodorous gas produced by domestic waste treatment have gradually become issues that need to be paid attention to. Malodorous gas will cause serious harm to the atmosphere and human body, and the harm is persistent. [0003] In recent years, my country has made great progress in the treatment of malodorous gases, and many different types of deodorants have been developed. However, the composition of malodorous gas is complex and difficult to control, among which the removal of mercaptan components is a great difficulty. Ordinary chemical deodorants are difficult to effectively absorb hydrogen sulfide and mercapta...
