Abstract
In this article, we report the family of robust layered sulfides K(2x)Mn(x)Sn(3-x)S(6) (x = 0.5-0.95) (KMS-1). These materials feature hexagonal [Mn(x)Sn(3-x)S(6)](2x-) slabs of the CdI(2) type and contain highly mobile K(+) ions in their interlayer space that are easily exchangeable with other cations and particularly strontium. KMS-1 display outstanding preference for strontium ions in highly alkaline solutions containing extremely large excess of sodium cations as well as in acidic environment where most alternative adsorbents with oxygen ligands are nearly inactive. The implication of these results is that simple layered sulfides should be considered for the efficient remediation of certain nuclear wastes.Entities:
