摘　　要：为了研究废油指纹分布特征,并对废油性质进行鉴定,采用气相色谱质谱联用仪对5种典型废油样中的正构烷烃、多环芳烃、生物标志类化合物信息及物理性质进行分析研究。结果表明:废制动机油样品中未检测出正构烷烃、甾烷和萜烷类化合物,为非矿物油,其他4种油样含有矿物油特有的指纹信息,通过物理性质比对判断为废矿物油。废齿轮油、自动变速器油、废机油2#中萜类化合物含量最为丰富,在废制动机油分布较为丰富;废机油2#的甾类化合物含量最为丰富,废齿轮油次之;废制动机油中不含有任何种类的生物标志化合物。多环芳烃的指纹分析中,废机油1#的萘类化合物含量最高,其他3种废矿物油菲类含量最高。研究成果对完善废矿物油指纹分布特征、性质鉴定具有重要意义。In order to study the fingerprint distribution characteristics of waste oil and identify the properties of waste oil,five typical waste oil samples were analyzed by GC-MS.The information and physical properties of n-alkanes,polycyclic aromatic hydrocarbons and biomarkers were analyzed and studied.The results show that no n-alkanes,steranes and terpanes are detected in the waste brake oil samples,which are non mineral oil.The other four kinds of oil samples contain the specific fingerprint information of mineral oil,which is judged to be waste mineral oil by physical property comparison.The terpenoids in waste gear oil,automatic transmission oil and waste engine oil 2#are the most abundant,and the distribution of waste brake oil is relatively rich;the steroids in waste engine oil 2#are the most abundant,followed by waste gear oil;the waste brake oil does not contain any kind of biomarkers.In the fingerprint analysis of PAHs,the naphthalene content of waste oil 1#is the highest,and the phenanthrene content of other three kinds of waste mineral oil is the highest.The research results are of great significance to improve the fingerprint distribution characteristics and property identification of waste mineral oil.
