Study on Optimization of Treatment Methods and Risk Assessment of Phosphate Esters in Surface Water
The pollution of phosphate esters in surface water has become a serious environmental problem,threatening the health of water ecosystem.Based on this,this study adopted a series of methods,including sample collection,pretreatment,chromatographic analysis,mass spectrometry and so on.Through the analysis and optimization of surface water samples at different sites,the results showed that high risk TEHP was found at A3,while other sites showed moderate risk,among which the moderate risk sites accounted for 57.14%of the total sites.Other compounds,however,had lower risk values.This study has important practical significance for the optimization of the treatment of phosphate esters.
