SPECTROSCOPIC STUDIES OF THE INTERACTION OF Eu(II1) WITH THE ROOTS OF WATER HYACINTH

摘要

The water hyacinth is a plant currently being used throughout the world, including sites within l km of the Chernobyl nuclear accident, for the removal of toxic metals from water. We have recently shown that the roots of water hyacinth will remove large quantities of Eu(III) from Water. In this study we were able to determine that carboxylic acids are responsible fOr binding the intracellular proportion of Eu(III) in the roots of water hyacinth using the techniques of Nuclear Magnetic Resonance (NMR) and Infrared (IR) spectroscopies.
