摘要: Abstract The self-diffusion coefficient, the spin-lattice relaxation times and ionic conductivity of lithium ions in liquid mixtures composed bis(2-ethylhexyl)amine (BEEA) bis(2-ethylhexyl)phosphoric acid (HDEHP) have been thoroughly investigated as a function composition temperature by NMR spectroscopy conductometry. While dependence diffusion coefficients follow same trend observed for those surfactant molecules, 1 H are remarkably different. behavior has interpreted terms occurring through its association with negatively charged HDEHP species, whereas rotational dynamics being decoupled from that gives T values lower than molecules characterized different dependence.
