| Abstract: | A method for the simultaneous determination of preservatives and sweeteners in drinks by high performance liquid chromatography was described.The experiments were carried out by EclipseXDB-C18（4.6mm×250mm,5μm） with methanol-0.02mol/L NH4Ac（30∶70,V/V,pH=6.0） as mobile phase at a flow rate 0.7mL/min and column temperature of 25℃.The UV detection wavelength was fixed at 230nm.The result indicated that the correlation coefficient of all subjects was between 0.9990 and 0.9998,the recovery was 98.40%—109.22%.The method is easy,sensitive,quick,reliable,repeatable and suitable for quality test. |
