Abstract
The interactions of VO2+ with phytate to form both soluble and insoluble complexes, have been studied by electronic absorption spectroscopy. A soluble 1:1 VO2+:phytate complex is formed at pH < 1. At higher pH-values insoluble complexes are produced. Two different solid complexes, obtained respectively at pH = 2 and 4, were isolated and characterized. The maximal bonding ratio of VO2+:phytate was found to be 4, on the basis of a pH binding profile.Entities:
