Chemical separation methods, such as extraction and chromatography, are based on chemical interactions between the mixture's components, or, to be more precise – the differences in the strengths of the interactions of the different materials in the mixture with another material which is not a part of it. Naturally, these interactions are ...
The results suggest that successive treatments of phlogopite mica heated under microwave radiation will rapidly remove K from the mica. Decreasing the amount of time required to prepare K-depleted phlogopite micas will make these materials more appealing as ion exchangers for separation of Cs from nuclear wastes.
