Abstract
The surface chemistry and physical properties of clay minerals are often very much dependent on the nature of the metal ions which balance the negative charge of the oxygen framework. The most abundant metal ions normally found in clays (silicon, aluminum, magnesium, and alkali and alkaline earth metals) are diamagnetic, but paramagnetic ions such as Fe3+ may also be found to substitute for silicon, aluminum or magnesium in tetrahedral or octahedral positions. A variety of paramagnetic ions or metal complexes, such as VO2+ or Cu(phen) 2+2 , can become part of a clay structure by replacing the interlayer alkali or alkaline earth exchange cations. Thus, it is only natural that electron spin resonance spectroscopy (ESR), sometimes called electron paramagnetic resonance (EPR), should be a useful tool in studying the behavior of metal ions in clays.
