Phase Transfer Extraction and Adsorption Methods,g on the subject the reader should consult previous books and reviews that have been written on the subject.. Although there has been a long term interest in metal separation in the mining industry, the recent greater emphasis on environmental concerns has led to a much broader interest in developin

Selective Extraction with Chelates, Macrocycles and Calixarenes,though this stability constant of the metal complex is not the only factor, it is still an important consideration. Since it is likely that the . environment contains complexants such as chloride, nitrate or sulfate ions, possibly at high concentrations, it is necessary that the added extractant is

Phase Transfer Extraction of Mercury,cient importance that we consider it alone. This importance results from the early recognition of the toxicological problems that are caused by mercury, and by the set of environmental problems that are posed by the unique chemistry of the element. Among the chemical properties of mercury that must

Extraction of Actinides and Lanthanides,en donor groups have been the most widely used. By contrast with transition metal and post-transition metal ions, actinides can frequently achieve higher coordination numbers than six. Therefore multidentates that can accommodate to high coordination numbers are good candidates for being extractants

Extraction of Anions and Oxyanions,und to a ligating group on the host, but for anions or uncharged molecules it may not be possible to get a direct interaction between the metal center and the atoms in the host. Although numerous molecules act as hosts and complexants for cations, fewer molecules function as hosts for anions.. Recen

Alkali and Alkaline Earth Metals, are important because they were the first compounds that allowed alkali metal ions to be solubilized in organic solvents. These compounds effectively extract alkali metal ions into an organic solvent from an aqueous phase, and by changing the cavity size within the macrocycle selectivity, between t
