Embodiment Construction

[0026] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, not to limit the invention.

[0027] In a specific embodiment, figure 1 It is a schematic diagram of the sensor structure according to this embodiment. The reaction cell 201 and the reaction cell 202 are assembled and connected in series to form a reaction cell group. The reaction cell group and the reference cell 3 are installed in the corresponding slots, and the two form an L-shaped angle of 90 degrees. A semi-transparent and semi-reflective beam splitter 1 is located The top end of the L-shaped 90-degree included angle. The length of each reaction cell can be determined according to the estimated concentration c of the component x and component y in the water body x and c y choice, respectively b x and b y . The length of the re...

Abstract

The invention discloses a wet chemistry micro in-situ sensor based on luminosity detection, which comprises reaction tanks, a reference tank, a light source, a detection element and a spectroscope, and can comprise that two reaction tanks are spliced and connected in series to form a reaction tank group to obtain light absorption values related to two parameters in a water body. A corresponding light absorption value data processing method is combined to realize wet chemical method in-situ measurement of two water quality parameters in the surface water body. The sensor is also matched with a reagent adding device which is used for adding a color developing agent into the water sample. The sensor is small in overall size and light in weight, and can be carried on a small unmanned mobile observation platform for use.

Description

technical field [0001] The application belongs to the technical field of environmental monitoring, and in particular relates to a wet chemical miniature in-situ sensor based on photometric detection. Background technique [0002] Water pollution caused by the development of human society has attracted increasing attention, and timely control of water pollution is of great significance. Nutrients are important water quality indicators, which are mainly determined by national standard methods and on-site / in-situ instruments. The standard method needs to bring the water samples collected on site back to the laboratory, add chemical reagents and analyze them with instruments (wet chemical method). Samples may be contaminated. In-situ detection can avoid possible contamination in sampling, sample transportation and storage, and pretreatment, and has the advantages of real-time and in-situ data acquisition. At present, there are many commercial nutrient in-situ detectors based ...
