摘　　要：An ion-pair reversed-phase high-performance liquid chromatographic method, using tetrabutylammonium bromide （TBAB） as ion-pair reagent, has been developed for the analysis of cyanuric acid （CA） in milk powder and swimming pool water. It was found that the effect of the concentrations of ion-pair reagent on the retention of cyanuric acid was different for standard solution and different real samples. The separation was carried out on a reversed-phase C18 column with 85 ： 15 （V/V） water-acetonitrile （ACN） containing different concentration of TBAB as mobile phase for different samples. The linear range of the calibration curve for CA was 0.1-100 mg·L^-1 The detection limits calculated at S/N=3 was 0.11 mg-L^-1 for the analysis of milk powder and 0.31 mg·L^-1 for the analysis of swimming pool water, respectively. The method was successfully applied to the analysis of CA in milk powder and swimming pool water.An ion-pair reversed-phase high-performance liquid chromatographic method, using tetrabutylammonium bromide （TBAB） as ion-pair reagent, has been developed for the analysis of cyanuric acid （CA） in milk powder and swimming pool water.
