Cations, light metal

The compatibility of each light metal cation with any low-melting molten salt electrolyte must be examined experimentally. It can be anticipated that at least some such combinations will have useable properties. 

It would be best if toxicity data were put on an absolute rather than a relative basis, since reference to a control unit would not be required. The advantage of defining quantitatively the metabolic rate-concentration curve (Figure 1) over the whole or most of its range is obvious. The initial attempts to do this for light metal cations are discussed later. 

Figure 1 shows that any substance can exert a toxic effect, and many have been reported as toxic in anaerobic treatment. However significant data exist for only three groups of substances— heavy metals, organic acids (pH), and light metal cations. 

Little work of significance was performed on the effect of light metal cations until the last decade. The early studies such as those of Buswell et al. (3), Rudolphs and Zeller 21), Fair and Carlson 13), Cassell and... 

Acclimation to the toxic effect of high concentrations of the light metal cations was significant. Figure 14 illustrates the extent of the acclimation observed.

Thermal conductivity and electrical conductivity The movement of mobile electrons around positive metallic cations makes metals good conductors. The delocalized electrons move heat from one place to another much more quickly than the electrons in a material that does not contain mobile electrons. Mobile electrons easily move as part of an electric current when an electric potential is applied to a metal. These same delocalized electrons interact with light, absorbing and releasing photons, thereby creating the property of luster in metals.
