Vanadyl compounds, molecular weight

Fish and Komlenic (1984) and Fish et al. (1984) have demonstrated that the vanadyl compounds associated with apparently high molecular weight fractions (2000+) observed by SEC-HPLC can, to a certain extent, be extracted as low-molecular-weight compounds with an aqueous pyridine solution. Nearly all of these extracted vanadyl compounds from either the... [Pg.130]
