For obtaining the nanosized inorganic materials on oxides of transition and rare earth elements, the most promising is the use of methods of "soft chemistry" based on synthesis from aqueous or non-aqueous solutions at relatively low temperatures. Their key advantages are: the possibility of obtaining products with controlled composition and micromorphology, efficiency, environmental acceptance and so on.

Technology Applications

Rare earth elements, i.e., lanthanides, are important components of many recently developed technology applications. However, their increasing use in the industrial sector, medicine, and agriculture over the last few decades has provided them with the title of “new pollutants”. Different methods are now applied for the removal of various pollutants from wastewaters, whereby the emphasis is placed on adsorption due to its simplicity, high efficiency, and low cost. In the present study, geopolymers prepared from coal ash were examined regarding their capacity for the adsorption of lanthanides from model solutions. The obtained results indicate the efficient removal of lanthanides by prepared geopolymers, depicting them as effective adsorbents for this group of elements.
