Scandium(III) adsorption isotherm collected for MICOF-33 at 298 K upon exposure to solutions of scandium(III) chloride hexahydrate dissolved in aqueous HCl (pH, ~5.5) with initial concentrations ranging from 2 to 500 ppm. The inset shows equilibrium adsorption data and a fit using a Langmuir model (R2 = 0.9998; Supplementary Section 3.1 and Supplementary Table 3 for details), yielding a saturation capacity of 52.7 mg g –1. R2, correlation coefficient; C e, ion concentration at equilibrium; q e, ion sorption capacity at equilibrium.
