The biscuit samples were extracted by 1% trichloroacetic acid solution and 2.2% lead acetate,and melamine was separated on a Hypersil ODS C_18 column (100 mm×4.6 mm,5 μm ). Acetonitrile and sodium 1-octanesulfonate solution(pH 3)(15∶85,V/V) were used as mobile phase at a flow rate of 1.0 mL·min~(-1). The detective wavelength was set as 210 nm by an ultraviolet detector.The temperature of column was 40 ℃. The linear ranges for melamine were 0.2-10 μg·mL~(-1). The average recovery rate of this method varied from 80.5% to 93.5% with the relative standard deviation of 7.7% (n=9) when blank sample was fortified standard working solution of 1,2 and 4 μg·mL~(-1). %K melamine %K biscuits %K high performance liquid chromatography (HPLC)
