Abstract

Abstract : A novel sulfur-functionalized metal–organic frameworkFJI-H12 has been developed, which can completely and selectively remove Hg(ii ) from water with high saturation, adsorption and distribution. Abstract : A new strategy that uses sulfur-functionalized metal organic frameworks (MOFs) for removal of Hg(ii ) from water has been developed. This strategy is based around a novel sulfur-functionalized MOFFJI-H12, which is composed of octahedral M6 L4 cages and free NCS − groups. At the same time, large-scale synthesis ofFJI-H12 microcrystals has also been carried out under very mild conditions. The resulting material can remove Hg(ii ) completely and selectively from water with high saturation, adsorption (439.8 mg g −1 ) and distribution coefficient (1.85 × 10 6 mL g −1 ) relative to other MOFs. More interestingly, a continuous and fast removal of Hg(ii ) from water has also been carried out using a column loaded withFJI-H12 microcrystals.
