Study On Fluorescence Spectrum Technology Of Organic Pollutants Of Refined Oil In Complex Mixture

With the continuous development of science and technology,as an irreplaceable energy source and chemical raw material,petroleum plays an important role in our social progress.However,in human activities,a large amount of oil and its products enter the natural environment,causing serious environmental pollution.Therefore,the rapid,efficient and accurate detection of oil pollutants plays an important role in protecting the environment in which we live.The purpose of this paper is to solve the problems of poor accuracy,cumbersome use,and inability to identify the type of contaminants that are present when using the instrument to detect oil contamination in water.A novel detection and signal processing algorithm for oil contamination in water based on fluorescence detection is proposed.It uses optical fiber transmission,charge coupled device spectroscopy,three-dimensional fluorescence spectrum standard discretization and spectral signal analysis.Firstly,the mechanism of fluorescence detection of oil contaminants in water is fully studied.Starting from the mechanism of photoluminescence,the radiation generated during the process of excitation,de-excitation and de-excitation of molecules or atoms is deeply studied.Secondly,the composition of mineral oil was analyzed to identify the components of the oil that could be excited to produce fluorescence.In order to ensure the true and effective test results,the influence of various factors of environmental factors on the in-depth study.Finally,CCD spectroscopy and three-dimensional fluorescence spectroscopy were used to obtain the mineral oil spectral information.The obtained spectral signal was processed by standard discretization,and the standard discretized three-dimensional fluorescence spectrum matrix data was processed through an alternating trilinear algorithm to realize the mineral oil type.Quickly identify and predict and verify its feasibility.
