Research on the Treatment of Fluorescent Organic Pollutants in Water Environment Based on Chemical Precipitation Method
When using chemical precipitation method to treat fluorescent organic pollutants in water environment,ammonium sulfate(NH4)2SO4 is used as the main precipitant and added to the pre-treated water sample for chemical precipitation reaction.The precipitate is separated from the aqueous solution by standing and centrifugation,and the adjusted water sample is left to settle for 1 hour to form and precipitate.Separate the formed sediment through a filter and separate the clarified liquid from the solid to obtain the processed water sample.Automatically record the fluorescence intensity data and generate a fluorescence spectrum.Inject it into a total organic carbon analyzer(TOC analyzer)to measure the organic content in the sample.Combined with the fluorescence intensity detection results,comprehensively evaluate the overall treatment effect of the water sample.The experimental results showed that after using the chemical precipitation method,the removal rate of most pollutants exceeded 80%,and the removal rate remained relatively stable without significant fluctuations.This indicates that the chemical precipitation based method for treating fluorescent organic pollutants in water environments has significant effects and can effectively remove various types of fluorescent organic pollutants under different conditions,with wide applicability.
