摘要目的：建立大体积进样、程序升温气化、气相色谱质谱联用测定饮用水中的土臭素的分析方法。方法：水中的土臭素用二氯甲烷萃取后大体积进样，程序升温气化、气相色谱质谱分析测定，选择离子定量。结果：在0-1000ng／L浓度范围内线性良好，相关系数为0．999，方法检测限为2ng／L，加标回收率在89％-97％之间，精密度RSD〈10％。结论：该方法灵敏度高、准确度好，满足生活饮用水中的土臭素的卫生检测要求。 Objective：A method for determination of geosmin in drinking water by PTV-GC/MS was developed. Methods： Geosmin in drinking water was extracted by dichloromethane. The extract was analyzed by GC/MS with a programmable temperature vaporizer in large volume injection mode. Selected ion mass method was used in quantitative analysis. Results：Within concen-tration range from 0 to 1000 ng/L, the calibration curve had a good linearity, the correlation coefficient was 0.999. The method detection limit was 2 ng/L. Recoveries were between 89% and 97%. Precision RSD〈10%. Conclusions：PTV-GC/MS is a sensitive and accurate method for determination of geosmin in drinking water. It is suitable for monitoring geosmin in drinking water.
