摘要
河流悬浮物上的有机污染物品种繁多，成分极为复杂，多环芳烃只是其中的一类，对这类复杂的环境样品进行分析鉴定相当困难．本文提出了一个简单而有效的预处理及预分离方法，将多环芳烃首先从复杂体系中分离出来，再采用ＧＣ／ＭＳ系统配合程序升温保留指数法，对运河苏南段的二个悬浮物样品中的多环芳烃组分进行了分析鉴定，共鉴定出多环芳烃５０余种．对检出的多环芳烃利用多重内标相对重量校正因子法进行了半定量分析．
There ane many kinds of organic pollutants in the suspended matter of the river,polycyclic aromatic hydrocarbon is one of them. It is difficult to determine the composition of the PAHs. This paper presents a simple and efficient procedure for the pretreatment of these complicated enviormental samples and the seperation of the PAHs from the suspended matter. PAHs then,are analyzed by GC/MS/DS system coupled with temperature-programmed retention index method. Two suspended matter samples, collected at South Jiangsu part of the Grand Canal,Jiangsu Province,China,are determinated by the method metioned above. More than fifty kinds of polycyclic aromatic hydrocarbons are identified,and some of them are semi-quantitative measured by the multi-inner-standard method.
