What is it about?
Silica-based urea-formaldehyde (SiO2/UF) composite material was prepared and impregnated with organophosphorus extractant, namely; 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester, for the removal of Eu(III) and Nd(III) from aqueous solutions. The sorption capacity of the impregnated SiO2/UF for Eu(III) and Nd(III) were determined and found to be 3.1 and 2.8 meq/g, respectively.

Why is it important?
The values of sorption capacity of silica–urea–formaldehyde composite material impregnated with ion quest 801 for europium and neodymium ions were compared with other sorbents obtained in the literature. The prepared impregnated composite has much higher sorption capacity than many other sorbents.
Perspectives
The prepared impregnated composite is an efficient sorbent media and recommended for removal of some lanthanide elements from aqueous solution.
