The enhancing effect of NaCl on Cd uptake was due to chloride complexation of Cd (Smolders et al., 1998). High salinity in soils increased the concentrations of chloride complexes of trace elements (such as CdCl or CdCl2°) in soil solution, which increased and correlated best with Cd uptake of both plant species as discussed above. In addition, salinity also affected plant root function, and Na competition with Cd for sorption sites in soil may be a possible contributor. 

The inherent toxicity of the particle will depend on its chemical composition. For example, a particle of CdCl2 can be expected to be more toxic than NaCl because of the known toxicity of Cd+2 (6). In the case of fibrous particles, the toxicity of the material will also depend on the size and shape of the fibers, with long, thin fibers being the most toxic (7.8). 

In view of Swalin s treatment of diffusion in liquid metals, the latter seems to be a better description. In binary mixtures such as NaCl-KCl the equivalent conductivities are a linear manner, but the KCl-CdCl2 mixture shows a marked negative departure from linear behaviour, probably because of the formation of the complex ion CdCh. ...

This conclusion is further strengthened considerably by the theoretical calculation of CBE originally performed by Pearson and Gray (102) and later on somewhat modified by Pearson and Mawby (8). Values of CBE are calculated according to three models, viz. the hard sphere model, the polarizable ion model and the localized molecular orbital model. Only the last one, treating the bonds as covalent, is able to account in a satisfactory way for the values found experimentally for such halides as HgCl2 and CdCl2. For LiCl and NaCl, on the other hand, an acceptable fit with the experimental values is obtained already by the hard sphere model, which certainly indicates a predominantly electrostatic interaction. 

Finally, Czobik et al. [4] reported that in the analyte—interferent systems Pb—CdCl2, Sn—CdCl2, Sn—CuCl2, Zn—PbCl2, Zn—CuCl2, and Zn—CdCl2, sulphuric acid and phosphoric acid successfully removed the interferences. Nitric acid was found to be less effective although it removed the interference in the Pb—NaCl system. 

In PbClg the lead ion occupies the centre of a trigonal prism with six CL ions at the corners and three outside the face centres. SrBr2 is similar (Fig. 215). But most dihalides form layer lattices. CdCl2 can be considered as an NaCl structure (p. 141) in which half the octahedral holes between the Cl atoms are unoccupied (Fig. 216).
