Description

Solid phase membrane extraction-gas chromatogram the tandem mass spectrum of organochlorine compound in a kind of water body Detection method
Technical field
The present invention relates to Water quality safety detection technology field, in more particularly to a kind of water body, organochlorine compound consolidates Phase membrane extraction-gas chromatogram tandem mass spectrum detection method.
Background technology
Gamma Hexaochlorocyclohexane, clofenotane are the organochlorine pesticides of a class difficult degradation, many insects are had tag, stomach toxicity, stifling and A certain degree of systemic action, about 2~20 years or so the half-life of organochlorine pesticide, can accumulate in vivo and pass through Food chain is transmitted, and causes serious threat to ecological environment and health.Although many countries are prohibited already and limit use, Due to Gamma Hexaochlorocyclohexane, clofenotane stable chemical nature, further investigation reveals that in the surrounding medium of domestic each department and have in human body residual Stay, some are even higher by standard regulation manyfold.Such as Min River water body Gamma Hexaochlorocyclohexane, the contamination characteristics application form open fire body six of clofenotane 66 and clofenotane mass concentration scope respectively 1.031-1.804 and 0.767-1.156ng/L.Organochlorine pesticide in soil Residual has directly harm to terrestrial life, also can be discharged into influence on water body aquatile by rainwash.Many chlorine connection in environment Benzene (PCBs) mostlys come from the production of industrial goods.The commodity production of PCBs starts from nineteen twenty-nine.Although the production of PCBs and application It has been prohibited in worldwide in 20 century 70s early stage, the production in whole world PCBs alreadys exceed 1,300,000 tons. Start to produce from nineteen sixty-five, end (production of PCBs is prohibited) in 1974, China about produces 10000 tons of PCBs.Additionally, The 1950's, China also constantly entered to suck the electric equipment of PCBs from other countries, and these also become between the eighties The potential source of PCBs pollutions in Chinese environmental.In soils and sediments, according to existing PCB data, PCB in China s dense Degree scope is 0.01~1840 μ g/kg.?《Water environment quality standard》In the total standard Limited Doses of 7 kinds of PCBs be 0.02 μ G/L, the Limited Doses of clofenotane are 0.2 μ g/L.In scholar's research reservoir area of Three Gorges water body, the residual level of PCBs and its environment are handed over Change, as a result show that the content range of PCBs in the water body of reservoir area is not detect~48.67ng/L.In eight big estuary water body of the Zhujiang River The content range of PCBs is 0.19~7.04ng/L.Waste electric products, deposit are in suspension, atmospheric sedimentation and waste water treatment plant Discharge is the significant contributor of water body PCBs pollutions.
As in environmental water sample, organochlorine compound concentration is extremely low, it usually needs could determine through enrichment.Traditional richness Catchment middle organochlorine compound method be liquid-liquid extraction method, cumbersome time-consuming, need to consume substantial amounts of organic solvent, And solid phase extraction because have simple to operate, consume that solvent is few and the high analysis for being widely used in pesticide of enrichment times in. Searching is a kind of simpler, and in the water body of environmental protection, the pre-treating method of organochlorine compound becomes study hotspot.Solid phase membrane extraction is made For one kind of Solid-Phase Extraction, the solid-phase extraction membrane used by it, large volume of water sample, and enrichment times can be processed faster High.In addition, solid phase membrane extraction directly can process water sample at the scene, convenient and swift stable.The instrument detection of organochlorine compound Technology has gas chromatogram, gas chromatography-mass spectrography etc..Gas chromatogram-electron capture detection is used as selectively highly sensitive The detecting instrument of degree, has higher sensitivity and accuracy to organochlorine compound detection, but is easily disturbed by impurity, qualitative not Enough accurate.In recent years, research worker has carried out the research to some Hekou Area organochlorine residues and distribution, but with regard to water body in The research of trace organochlorine compound residual is few.
