Fig. 3: Iodine adsorption experiments.

Time-dependent I₂ vapor uptake by 3·6X (X = Cl⁻, Br⁻, I⁻, PF₆⁻) in a g g⁻¹ and b mol mol⁻¹, respectively. c Time-dependent UV/vis absorption spectra of a solution of I₂ in n-hexane (2 mM, 3 mL) upon addition of 5 mg 3·6I. d Iodine removal efficiency in solution (2 mM, 3 mL) at various times by 5 mg 3·6X (X = Cl⁻, Br⁻, I⁻, PF₆⁻), monitored by change of I₂ absorbance at 522 nm.
