Abstract

The invention discloses a preparation method of a formaldehyde sensitive type hyaluronic acid film sensor. Firstly, a probe compound KD-XA01 and a polymer P (St-alt-Man) are synthesized respectively, polymer colloid particles cladding a probe are prepared in a self-assembly manner in a solvent and added into a hyaluronic acid matrix film formation solution, and the formaldehyde sensitive type hyaluronic acid film sensor is prepared with a tape casting method. Hyaluronic acid is a natural high polymer material, is biodegradable and has a certain promotional value.

Description

technical field [0001] The invention belongs to the field of natural polymer film materials and chemical sensors, and in particular relates to a preparation method of a formaldehyde-sensitive hyaluronic acid film sensor. Background technique [0002] Formaldehyde is an irritating and suffocating colorless gas at room temperature. It is extremely harmful to the human body and is one of the environmental pollutants that has received increasing attention. In my country's list of priority control of toxic chemicals, formaldehyde ranks second. Therefore, it is particularly important to establish a formaldehyde determination method that is easy to operate and has high precision. The most commonly used method for detecting formaldehyde is colorimetry, which can be divided into colorimetric acid method, acetylacetone method, AHMT colorimetric method, etc.; in national standards, the preferred method for detecting formaldehyde in textiles, food, and air is colorimetry. The most wide...
