Abstract

When using UV-Vis spectroscopy to detect water quality parameters, the scattering of suspended matter in water will cause the overall spectral curve to rise nonlinearly, which will affect the accuracy of the experimental results. Aiming at the problem that the spectrum is easily interfered by the light scattering of suspended matter, a total light scattering compensation method based on Mie scattering theory is studied to compensate for the interference of spectral turbidity. The extinction spectrum of , and then differentiated from the original spectrum, to achieve accurate compensation for turbidity interference, and this method does not require prior data support, which can improve the detection accuracy of organic matter content by UV-Vis spectroscopy.
