Abstract

The invention relates to a preparation method of an intelligent supramolecular aquagel for detecting formaldehyde in interior decoration and wastewater, which comprises the following steps: (1) weighing alpha-cyclodextrin powder, and adding ultrapure water to prepare an alpha-cyclodextrin water solution; (2) adding a Tyloxapol liquid, and adding ultrapure water to prepare a Tyloxapol water solution; and (3) taking the alpha-cyclodextrin water solution and Tyloxapol water solution, adding ultrapure water until the alpha-cyclodextrin concentration in the gel is 90-130 mg.mL<-1> and the Tyloxapol concentration is 15-50 mg.mL<-1>, carrying out ultrasonic dispersion, and standing. The preparation method is simple, and the used raw materials have favorable biocompatibility and are friendly to application environments. The intelligent supramolecular aquagel has the advantages of low cost and no toxic byproducts.

Description

technical field [0001] The invention relates to a preparation method of an intelligent supramolecular hydrogel used for detecting indoor decoration and formaldehyde in waste water, belonging to the field of new materials. Background technique [0002] Relevant data show that volatile organic compound pollution has become the cause of various diseases, among which formaldehyde pollution is a major source of pollution. Formaldehyde is mainly manifested as a stimulating effect on the skin and mucous membranes. When it reaches a certain concentration indoors, it can cause chest tightness, dermatitis, asthma and other physical discomfort. High-concentration formaldehyde is a toxic substance that can seriously affect the nose, pharynx, and throat of the human body. . Formaldehyde is often used in organic synthesis, dyes, wood processing and textile industry. There will be a certain amount of formaldehyde in the wastewater of industrial areas, which will lead to groundwater pollut...
