The research has emphasized on enhancement of selectivity for extracting metal ions with similar charge; i.e. ions of metals in the lanthanide and actinide series which are found in certain parts of the country. Both chemical reaction and simultaneous extraction/stripping have been utilized for the research. Separation of gaseous mixtures with adsorption has also been studied in order to reduce energy consumption of separation processes, especially removal of dilute impurities and relatively low temperature separation. In addition, various adsorbents have been produced from local resources; i.e. volcanic rock and agricultural waste, under appropriate conditions, in particular at low temperature.
