气相色谱-质谱联用法测定聚氨酯类防水涂料中8种芳香族化合物
Determination of Eight Aromatic Compounds in Polyurethane Waterproof Coating by Gas Chromatography-Mass Spectrometry
摘要
Abstract
A simultaneous determination method was developed for the quantification and confirmation of 8 aromatic compounds, including benzene, toluene, ethylbenzene, p, m-xylene, o-xylene, phenol, naphthalene and anthracene, in polyurethane waterproof coating by gas chromatography -mass spectrometry (GC - MS). The extraction and separation efficiencies of targeted compounds were investigated by using organic solutions of ethyl acetate, butyl acetate, acetone, acetonitrile and etha-nol. The 8 aromatic compounds were extracted with ethyl acetate, and determined by GC - MS under the selected ion mode (SIM) using undecane as the internal standard. The calibration curves showed good linearities in the range of 0.01 -2.40 g/L with correlative coefficients (r) larger than 0.99. The average recoveries were in the range of 95% - 109% with relative standard deviations (RSD, n = 6) of 0.7% -4.9%. The limits of detection(LOD, S/N≥3) were all 0. 001 g/kg. This method was applied in the determination of aromatic compounds in 10 polyurethane waterproof coatings on sale with satisfactory results. The method shows the advantages of good reproducibility, high sensitivity and simple operation.关键词
