Abstract: front page image
(EN)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 m2/g, a pore diameter in the range 70-150 Angstroms and a pore volume ≥ 0.25 cm3/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.
(FR)La présente invention concerne un adsorbant adapté à l'adsorption de métaux lourds, constitué d'un support fonctionnalisé par thiols, où l'adsorbant présente une surface BET comprise dans l'intervalle 200-500 m2/g, un diamètre de pore compris dans l'intervalle 70-150 angströms et un volume de pore ≥ 0,25 cm3/g. L'adsorbant peut être employé pour éliminer les métaux lourds comme le mercure et/ou l'arsenic des courants d'eaux usées comme les effluents industriels ou les effluents d'épurateurs de fumées.
