Simultaneous determination of seven ethers in surface water by headspace-gas chromatography
A headspace-gas chromatography method for simultaneous determination of methyl tert-butylether,isopropyl ether,ethyl tert-butylether,methyl tert-amyl ether,anisole,phenyleether and diphenyl ether in surface water was established.The addition amount of sodium chloride and headspace temperature were optimized.The linearity of the seven ethers was good in the concentration range of 3.00~80.0μg·L-1,and the detection limits were 0.13~0.27μg·L-1.The recoveries were 89.0%~106.0%.RSDs of the six tests were all lower than 5%.This method is simple to operate,low detection limit,good precision and accuracy,and can meet the detection requirements of methyl tert-butyl ether,isopropyl ether,ethyl tert-butyl ether ether compounds in surface water.
