Adsorbents

摘要

An adsorbent suitable for heavy metal absorption is described, comprising a thiol-functionalised support containing a stabilising amount of an alkaline metal reacted with said thiol functionality. The adsorbent may be used to remove heavy metals e.g. mercury and/or arsenic, from wastewater streams such as produced water or flue gas scrubber waters.
