Impregnation of ionic liquid into solid support for removal of Nd and Gd ions from aqueous solution.

What is it about?

Impregnation of cyphos IL-104 as an ionic liquid into silica was carried out for the removal of neodymium and gadolinium ions from aqueous solution. Comparative sorption behavior of silica and impregnated silica for sorption of neodymium and gadolinium ions was investigated.

Why is it important?

Modification of silica by impregnation of cyphos IL-104, as an ionic liquid, was carried out. Separation and recovery of lanthanide elements from radioactive and industrial wastes are important both environmentally and economically, therefore, this work focused on sorption of neodymium and gadolinium ions from aqueous solutions. The modification process enhanced the percent uptake of neodymium and gadolinium ions from 18 to 97% and from 20 to 99.7%, respectively. The impregnated silica by ionic liquid exhibited a high sorption capacity for for Nd3+ and Gd3+ ions relative to other sorbents as compared to the state of the art in the literature.
