Spatial confinement of a cationic MOF: a SC–SC approach for high capacity Cr(vi)-oxyanion capture in aqueous solution†
Abstract
A water-stable cationic MOF could be used as a single crystal container to capture Cr(VI)-oxyanions via ion exchange with high capacity and selectivity. It is the first report that demonstrates that CrO42− ions could be traced and confirmed via a single-crystal to single-crystal (SC–SC) pattern.
