Abstract

Heavy metal ion remediation properties of the layered sulfide material K_2xMn_xSn_3-xS₆(x=0.5-0.95) (KMS-1), which was shown to be an excellent sorbent for strontium ions was investigated. KMS-1 effectively removed mercury, lead, and cadmium from water with a capacity and selectivity that allowed their concentration to be reduced to well below the government allowed safe drinking levels. The tests were carried out with potable water having pH ≈ 6.5 and was intentionally contaminated with environmentally relevant (highly toxic) levels of mercury, lead, and cadmium. KMS-1 effectively reduced the concentration of all heavy metal ions down to their acceptable limits in a short period of time. The study revealed that the KMS-1 binds soft heavy elements by strong M-S bonding and is superior as heavy metal ion sorbent over known materials.
