  • Title: [HG-AFS determination of selenium in Moringa oleifera].
    Author: Huang GQ, Xiao ZJ.
    Journal: Guang Pu Xue Yu Guang Pu Fen Xi; 2007 Feb; 27(2):383-5. PubMed ID: 17514982.
    Abstract:
    The Se content in Moringa oleifera was studied by hydride generation atom fluorescence spectrometry (HG-AFS) with wet digestion. The effects of the way of digestion, the work condition of apparatus, the reaction medium and acidity, and the reducing agent and masking agent on the determination of Se were investigated. And the operating condition of apparatus was optimized. The results showed that the detection limit of Se in this method was 0.42 ng x mL(-1) in the linear ranger of 0-120 ng x mL(-1), the relative standard deviation was 3.53% (n = 11), and the recovery of the method was 95.2%-104.6%. It was showed that the method was very sensitive, simple, rapid and accurate.
