New dendritic ionic liquids (DILs) for the extraction of metallic species from water

Author affiliations

Abstract

Four dendritic ionic liquids (DILs) have been easily synthesized from 3rd generation PAMAM and PPI: PAMAM G3 NH3+ Tf2N (1), PPI G3 NH3+ Tf2N (2), PPI G3 NH2 Me+ BF4 (3) and PAMAM G3 NH2 Me+ BF4 (4). These DILs are fully characterized by spectroscopic methods (1H, 13C and 19F NMR) and elemental analysis. Compound 1 is hydrophobic while compounds 2–4 are hydrophilic. In order to apply these DILs for the extraction of aqueous metallic cations (Cu2+, Ni2+, Pb2+, Cd2+, and Ag+), liquid–liquid extraction and dialysis were performed. ICP technology has been used to reveal the amount of metallic cation that has been extracted. Compound 1 shows the best results especially for the extraction of Cu2+, Pb2+ and Ag+ cations (up to 98%). Two processes have been employed: liquid–liquid extraction and dialysis.
