Objective To establish a method for the detection of cyclicaldehyde compounds in drinking water sources, in order to practice highquality development and improve the technical support of public servicequality. Methods Quantitative detection method of cyclic aldehydecompounds in drinking water by using SPME-GC-MS/MS were established.Results The results show that the optimal conditions for SPME aimed atcyclic aldehyde compounds in drinking water are an incubationtemperature of ${50}^{\circ }\mathrm{C}$ , a rotationalspeed of ${500}\mathrm{r}/\mathrm{{min}}$ , anincubation duration of ${15}\mathrm{\;{min}}$ , followed by asample extraction time of ${20}\mathrm{\;{min}}$ . The detectionlimits of this quantitative detection method were 2.87~4.67 ng/ L, therelative standard deviation were 6%~16%, the recoveries were 70.7%~115%.A specific water sample was collected to ascertain that the keyodor-causing compound was2-EDD, exhibiting concentrations ${32}\mathrm{{ng}}/\mathrm{L}$ . Conclusion This method can accurately and swiftly identify key odor-causingcompounds in drinking water.
