Fig. 3: Monovalent ion selectivity in vermiculite membranes with different intercalated ions.
From: Tuneable ion selectivity in vermiculite membranes intercalated with unexchangeable ions
a Ion permeability through vermiculite membranes intercalated with Zr⁴+, La³+, Ir⁴+, and Sn⁴+, revealing two distinct selectivity sequences. Inset, statistics of Young’s Moduli of membranes obtained from atomic force microscopy measurements. b X-ray diffraction spectra of intercalated membranes after 24 h in LiCl, all showing an interlayer spacing of ≈14.8 Å within experimental scatter. c Li+ permeation vs. time for membranes intercalated with different unexchangeable ions. Error bars, standard deviation from at least ten samples. Dashed lines, guide to the eye.
