a, Calculation of both electronic binding energies (Eb) and Gibbs free-energy (ΔG) changes of adsorption of Pb2+ by neutral and deprotonated DMDP and EDTMP at room temperature (25 °C) and 50 °C. All energies are in units of kJ mol−1. b, Schematic of binding configurations of Pb2+ ions with deprotonated DMDP and EDTMP. Configurations were obtained based on density functional theory calculations.
