SORBENTS

摘要

A sorbent is described comprising a thiol functionalised silane supported on a shaped support, said sorbent having a mean crush strength = 0.5kg and a tapped bulk density in the range 0.4 to 0.8 kg/litre. The sorbent 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.
