Preferential affinity of calcium ions to charged phosphatidic-acid surface from a mixed calcium/barium solution: X-ray reflectivity and fluorescence studies

Wei Bu, Kevin Flores, Jacob Pleasants +1

X-ray reflectivity and fluorescence near total reflection experiments were performed to examine the affinities of divalent ions ($\mathrm{C}{\mathrm{a}}^{2+}$ and $\mathrm{B}{\mathrm{a}}^{2+}$) from aqu…
