Abstract

A theoretical study of alkaline earth extraction using a 15-crown-5 derivative has been carried out. The selectivity of the crown ether derivatives to extract alkaline earth metal cations (Be2+, Mg2+, Ca2+) is studied by Density Functional Theory (DFT). The DFT calculations use 6-31G(d) and LANL2DZ basis set at the B3LYP level of theory. The selectivity of the 15-crown-5 derivative to bind alkaline earth metal cations is assessed based on the interaction energy (ΔE) of the addition of the substituent affecting the crown ether’s selectivity. The electron donor group can increase the selectivity of the crown ether to bind the metal cations. Based on the interaction energy, charge transfer, and electron distribution in HOMO-LUMO, it can be concluded that the selectivity of the 15-crown-5 derivative to extract the metal ions increased by Be2+Mg2+ > Ca2+.
