Title: Aqueous sulfate separation by crystallization of sulfate–water clusters

An effective approach to separating sulfates from aqueous solutions is based on the crystallization of extended [SO4(H2O) 52-]n sulfate–water clusters with a bis(guanidinium) ligand. The ligand was generated in situ by hydrazone condensation in water, thus avoiding elaborate syntheses, tedious purifications, and organic solvents. Crystallization of sulfate–water clusters represents an alternative to the now established sulfate separation strategies that involve encapsulating the “naked” anion.
