Extraction and determination of total vanadium (V) and V species in various samples were performed. The toxic and biological effects of V species depend on the different chemical forms in a sample. Acid digestion and microwave digestion methods were investigated for the extraction of total V. Ethylenediaminetetra acetic acid (EDTA) and sulfuric acid were also studied for the extraction solvent of V species. For the separation of V (IV) and V (V), the composition and flow rate of the eluent (EDTA, Tetrabutylammonium phosphate (TBAP) and methanol) were investigated and optimized with the ion chromatography. The separated V species were detected by inductively coupled end-on-plasma atomic emission spectrometry. The stability of the V species was affected by the sample pH. The V species in a V-enriched apple was V (IV), and its concentration was 0.61 mg/kg.
