Abstract

The invention provides a method for measuring polycyclic aromatic hydrocarbon (PAHs) of sea water in a flow injection chemiluminescence way. The method adopts the scheme that the PAHs of the sea water is quickly enriched and eluted in an enrichment and elution way; and a chemiluminescence signal is detected via a chemiluminescence system formed by super oxidized oxalate, hydrogen peroxide and the PAHs, so that the method for measuring the PAHs of the sea water in the flow injection chemiluminescence way is achieved. The method for measuring the PAHs of the sea water has characteristics of site operation, speediness, simplicity and sensitivity.

Description

technical field

[0001] The invention relates to the technical field of environmental chemical monitoring, in particular to a method for measuring polycyclic aromatic hydrocarbons in seawater. Background technique

[0002] Trace organic pollutants in seawater - polycyclic aromatic hydrocarbons (Polycyclic Aromatic Hydrocarbons, PAHs) have been included in the list of priority monitoring pollutants due to their persistence, bioaccumulation and long-distance transport characteristics, and are important for routine monitoring of marine water quality. parameter. Traditional methods mainly use large-scale equipment such as gas chromatography (GC), liquid chromatography-mass spectrometry (HPLC-MS) and gas chromatography-mass spectrometry (GC-MS). The samples need to be processed in the laboratory after complex pretreatment. for separation detection. Seawater samples have a complex matrix and high salinity, and the pretreatment process of the samples takes up more than 60% of the ...
