Problems solved by technology

Common polycyclic aromatic hydrocarbons include pyrene, pyrene butyric acid, etc., but the fluorescence intensity of such indicators will decrease after a period of time, and pyrene derivatives are generally carcinogenic and teratogenic, and will emit toxic gases when heated. Extremely harmful, even a small amount will pollute groundwater and drinking water, and once it enters the organism, it will interfere with the normal reproduction of cells

Description

technical field [0001] The invention relates to a preparation method of a dissolved oxygen fluorescent sensing film. Background technique [0002] Oxygen is an important element to maintain the survival of organisms, human and animal life activities, metabolism, etc., and requires aerobic participation in biological and chemical processes. Therefore, the development of an in-situ, fast and accurate measurement Dissolved oxygen instrumentation is essential. In terms of the marine environment, measuring water quality and studying the self-purification ability of water bodies are also based on the determination of dissolved oxygen content. [0003] The testing methods of dissolved oxygen are: iodometric method, electrode method and fluorescence quenching method. Iodometric method is the national standard method for measuring dissolved oxygen, but it has the disadvantages of cumbersome operation, long time-consuming, and inability to realize online measurement. The electrode ...
