| Abstract: | The method for determination of Acrylamide in carbohydrate-rich fried food by ion-chromatography. The sample was diluted and accomplished with a Dionex Ion Pac ICE-AS1(4×250mm)column.UV/Vis Detection 202nm.7/3(V/V)water/acetonitrile as isocratic mobile phase at a flow rate of 0.15mL/min.The correlation coefficient was 0.9993,Limit of detection for the method was 0.010 mg/kg.The recoveries were 80.2%～99.1%.This method has as vantages of simplicity to prepare the samples,no interference and high sensitivity. |
