Study on Bio-absorptance and Determination of Harmful Element Arsenic in Wheat

Abstract

Abstract: Objective: Detect the content of arsenic in soil and wheat with study on bio-absorptance of arsenic. Methods: Determination of arsenic in samples by atomic fluorescence spectrometry. Results: In the given conditions, the determination range of standard curve of arsenic is 0～80μg/L with r>0.999, while detection limit is 0.07μg/L. The RSD of detect standard solution is 1.4%(n=11). The recovery between 91.57% and 107.1%. Conclusion: The bio-absorptance of arsenic in wheat is increscent with content of total arsenic in soil, but not more than 1%. The method is simple, accuracy and rapid. It has been applied to the determination of arsenic in soil and wheat with satisfactory results.
