the molecular ion lead to different mass spectra for each isomer. The gas phase infrared spectra exhibit isomer specific bands in the spectral region between 900 and 700 wave numbers. A synthetic mixture of dinaphthylsulfones was used for isomer identification and the assignment of the gas chromatographic retention behaviour of the dinaphthylsulfone isomers. Quantitative GC/MS analysis of dinaphthylsulfones
易北河及其支流Havel,Spree和Mulde的颗粒物的气相色谱-质谱(GC / MS)分析显示,一组三种二萘砜异构体是沉积物和悬浮颗粒物(SPM)污染物。二萘砜的质谱特征是分子离子(m / z 318)和萘基碎片离子m / z127。分子离子中HSO(2)和C(10)H(7)O的损失导致每种异构体的质谱不同。气相红外光谱在900和700波数之间的光谱区域中显示异构体特定的波段。二萘基砜的合成混合物用于异构体鉴定和二萘基砜异构体的气相色谱保留行为分配。对44个沉积物和SPM样品中二萘砜的GC / MS定量分析提供了有关易北河排水系统中二萘砜的总体分布和不同来源的全面信息。结果表明这些化合物长时间排放,并且在厌氧沉积物中具有环境稳定性。
