Problems solved by technology

Although this technology can effectively obtain the two-dimensional profile information of dissolved oxygen in sediments, it uses highly toxic solvents such as toluene, chloroform and refractory materials such as polystyrene in the preparation process of the sensing film, and mass production will be harmful to the environment and human body. Therefore, it is very important to develop a simple, efficient, environmentally friendly and high-performance preparation method and rapid detection method for dissolved oxygen.

Abstract

The invention discloses a preparation method of a dissolved oxygen fluorescence sensing film and a sediment-water interface dissolved oxygen two-dimensional dynamic distribution detection method, canaccurately obtain concentration dynamic change information of sediment-water interface two-dimensional and high-resolution (micrometre level) dissolved oxygen, and is suitable for the technical fieldof detection of sediment-water interface dissolved oxygen.

Description

technical field [0001] The invention belongs to the technical field of detecting dissolved oxygen in water body sediments, and in particular relates to a simple method for preparing a dissolved oxygen fluorescent sensing film and a method for detecting two-dimensional dynamic distribution of dissolved oxygen at a sediment-water interface. Background technique [0002] Oxygen is the basis of life. Not only is it essential for the survival of individual animals, but it also regulates the global cycle of key nutrients (nitrogen, phosphorus, sulfur, iron, manganese and other metals) and carbon. In the ocean, oxygen levels in the open ocean and coastal waters have been declining for at least the past half century, largely due to human activities increasing global temperatures and releasing nutrients into coastal waters. These changes promote microbial respiration and accelerate oxygen consumption, reduce the solubility of oxygen in water, and further reduce the rate of oxygen re...
