Estimate the densities of pollutions in water quality monitoring systems based on UV/vis spectrum
UV/vis spectrometric quantification is widely applied in water quality monitoring systems.The UV/vis spectrum contains a huge amount of information about the water composition so that it can be used to measure the density of substances.However,the traditional methods to estimate densities using spectrum based on Lambert-Beers law become invalid in UV/vis spectrum because of the strong correlation among the absorption ratio of different wavelengths in the UV/vis spectrum.So we need to find a new estimating algorithm for water quality monitoring systems based on the UV/vis spectrum.In this paper,we analyze the traditional estimating algorithms.After that,we design an efficient estimating algorithms for water quality monitoring systems and evaluate it through orthogonal experiments.
