Description

technical field [0001] The invention relates to a device and method for long-term in-situ detection of complex water bodies based on spectroscopy. Background technique [0002] Since the 1980s, the two technologies that have decisive influence on water quality monitoring are spectral analysis technology and chemical measurement technology. [0003] If subdivided, it can be divided into chemical analysis technology, atomic spectroscopy technology, chromatographic separation technology, electrochemical analysis technology, biosensing technology and molecular spectroscopy technology; among them, the water quality analyzers of the first three have large volume, sampling, testing Long cycle, high cost and other issues. [0004] Although water quality analyzers based on electrochemical analysis technology and biosensing technology are portable, they have problems such as short service life and high maintenance costs. [0005] Spectral analysis technology is the most widely used ...
