Evaluation and Interpretation of the Experimental Data

An example of exploiting chemisorption in radiochemistry of heavy elements was given by the adsorption studies of the atoms of heaviest actinoids on refractory metals to judge the metallic valence of trace elements see Sect. 1.5.2. Another case of interest was the high adsorption energy of some molecular halides on the surface of alkali halides. It takes place owing to the formation of complexes like K2ZrCl6, which are well known as bulk phases see Sect. 5.1.2 below. 

In principle situations intermediate between physisorption and chemisorption can also occur they can be discussed only on an individual basis.
