摘 要: | 采集了商丘市包河6个位点的表层沉积物,用色谱-质谱对正构烷烃进行了分析,利用正构烷烃碳数分布特征和CPI指标等,对该市区的正构烷烃来源进行初步探讨。结果表明,正构烷烃碳数分布范围多数在nC13-nC31之间,分布类型只有一种,即高分子碳范围,碳优势指数为nC29,1

Abstract: | Six surface sediments from Baohe River were collected in Shangqiu City.The component of n-alkanes was analyzed by gas chromatograph-mass spectrometer. The source of n-alkanes was discussed by its distribution characteristics and CPI index.The result showed that n-alkanes was in the range of nC13-nC31.N-alkane distribution patterns were characterized by one mode.High molecular range for nC29 being MH,1CPI 3 and the value of CPI1 close to 1 illuminated the origin of n-alkanes from terrigenous plant,exhaust gas discharged from vehicles and incomplete burning of oil products.Our results indicated the caution for the protection of Baohe River. |
