Metal Ions and Complexes Sorbed Onto Solids

3 Metal Ions and Complexes Sorbed Onto Solids. - The Li and Na NMR spectra of clay suspensions in water have been used to show how the smectite structure and the nature of the alkali counterions modulate the quadrupolar interaction. The surface modihcation of Y-AI2O3 by Na+ has been studied by H/ Na double resonance NMR techniques. The organic functionalisation of mesoporous molecular sieves with Grignard reagents has been investigated by C and Si NMR spectroscopy.  

Scandium methyl surface species generated by treating MCM-41 silica with [Sc N(SiHMe2)2 3] THF, [MesAl] and THE have been identified by H and Si NMR spectroscopy. The transport of Gd + through an ion exchange column has been investigated using MRI.
