The invention discloses a method for determining decyl methyl ammonium chloride in soil. The steps of freeze drying, acidified organic solvent extraction and Florisil soil purification are adopted asa soil sample pretreatment technology. The UPLC-MS/MS is used as a detection technology of a sample. The combined technology is used for analyzing decyl methyl ammonium chloride in typical soil in China. The method has the technical advantages of simplicity, convenience, accuracy and high selectivity, provides a background technology for evaluating the pollution condition of decyl methyl ammoniumchloride in a soil environment, and can also be applied to qualitative and quantitative detection research of decyl methyl ammonium chloride in other types of soil inside and outside a laboratory. 本发明公开了一种测定土壤中癸甲氯铵的方法，采用冷冻干燥+酸化有机溶剂提取+Florisil土净化作为土壤样品前处理技术，采用UPLC-MS/MS作为样品的检测技术，该组合技术分析我国典型土壤中的癸甲氯铵，具有简便、准确、高选择性的技术优势，为评估土壤环境中癸甲氯铵污染状况提供背景技术，该方法也可应用于实验室内外其它类型土壤中癸甲氯铵的定性和定量检测研究。
