【Abstract】 A method for quantitative determination of Arsenic in h ea lth food by Hydride Generation-Atomic Fluorescence Spectrometry. The limit of de tection was 0.1μg/L,the recovery rates were 88%-102%,linear calibration curve for Arsenic were measured within the range of 0-120μg/L and the correlative coe fficient was 0.9996; the coefficient of variation for sample detection were 3.9% -7.4%.更多还原
