皮革厂颗粒相污染物中有机成分谱的研究

调查了珠江三角洲典型皮革厂生产过程中不同车间PM₁₀的污染水平，并采用超声萃取和GC-MS联用技术研究了PM₁₀中半挥发性特征有机污染物的含量和成分谱.在所采集的PM₁₀样品中共检测出46种有机化合物，包括苯酚类、醇类、多环芳烃类、酸类、酰胺类和酯类等；真皮水场车间、真皮涂饰车间和人造皮革车间的PM₁₀浓度分别为678.5、 454.5和498.6 μg·m^-3，其颗粒相中有机物质量浓度分别为10.04、 6.89和14.21 μg·m^-3；真皮水场车间以酯类和酰胺类物质所占比重较大，分别为43.47%和36.51%，真皮涂饰车间以酯类和醇类物质所占比重较大，分别为52.52%和16.16%，人造革生产车间以酯类和酰胺类物质所占比重较大，分别为57.07%和24.17%；在得到的具体成分谱中，水场车间以9-十八碳烯酰胺含量最高，为26.15%，真皮涂饰车间以邻苯二甲酸二辛酯的含量最高，为44.19%，而人造革车间的丁烯二酸二(2-乙基己基)酯和1-羟基哌啶含量明显高于其它2个车间.

Research on Source Profile of Aerosol Organic Compounds in Leather Plant

Through investigating current air pollution condition for PM_(10) in every factories of different style leather plants in Pearl River Delta,characteristic profile of semi-volatile organic compounds in PM_(10) emitted from leather factories and their contents were researched by using ultrasonic and gas chromatography and mass spectrum technology.The 6 types of organic compounds containing 46 species in total were found in the collected samples,including phenyl compounds,alcohols,PAHs,acids,esters and amides....
