The invention relates to the technical field of chemical substance detection, in particular to a method for detecting dibutyl sebacate and acetyl tributyl citrate in a film material. The method comprises: weighing a to-be-detected film material and carrying out extraction by using an organic solvent to obtain an extracting solution; and detecting the extracting solution by using gas chromatography-mass spectrometer. The method is operated simply and easily; the result is accurate and reliable; the potential safety hazard in the film material can be discovered timely to realize an early warningeffect; and a technical support is provided for the risk monitoring of membrane material packaging products in China. The method has the broad application prospects and great economic and social values. 本发明涉及化学物质检测技术领域，特别涉及一种膜材料中癸二酸二丁酯和乙酰柠檬酸三丁酯的检测方法：称取待检膜材料，使用有机溶剂提取，得到提取液；提取液使用气相色谱-质谱联用仪进行检测。操作简便易行，准确可靠，及时发现膜材料存在的安全隐患，起到预警作用，为了我国膜材料包装产品风险监测提供技术支持，具有广泛的应用前景及较高的经济和社会价值。
