An adsorbent suitable for heavy metal adsorption is described, comprising a thiol functionalised support wherein the adsorbent has a BET surface area in the range 200-500 m 2 /g, a pore diameter in the range 70-150 Angstroms and a pore volume ≥ 0.25 cm 3 /g.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. |
