| Abstract: | A method for simultaneous determination of acesulfame,aspartame and benzoic acid in several drinks was established by high performance liquid chromatography（HPLC）.The optimal conditions were confirmed as follows:Diamonsil-C918)（250mm×4.6mm,5μm） column with 0.02mol/L ammonium sulfate-acetonitrile-phosphate（80:20:0.02,V/V/V） as mobile phase at a flow rate of 1.0mL/min.The UV detection wavelength was 210nm.The recoveries were in the range of 94.5%-101.5%,and the precisions were less than 3%.The simultaneous determination of acesulfame,aspartame and benzoic acid in carbonated drinks,tea drinks and orange juice was achieved. |
