Efficient removal of mercury from acidic solutions of HgCl2 by sorbents prepared from vegetable oils by inverse vulcanization
Original language description
Mercury is a dangerous toxic element for the environment. Incineration of municipal solid waste (MSWI) belongs to important sources of Hg-emissions today. Conversion of mercury and mercury compounds from soluble and toxic forms into water insoluble/non-toxic form of HgS is needed in waste residues from flue gas cleaning. Gaseous HCl and a significant part of HgCl2 vapors present in flue gas from MSWI can be removed from flue gas by absorption into hot water. Efficiencies of Hg2+ removal from acidic water solutions by means of sorbents prepared by catalyzed reaction of sulfur with vegetable oils (inverse vulcanization) were studied. These kinds of sorbents were tested and nfound to be exploitable for removal of mercury ions from water solutions, particularly from acidic solutions containing HCl at higher temperatures (50 – 75 oC), also in presence of salts of some other metallic elements (Fe, Zn, Ca). Mercury adsorbed on such sorbents changes relatively quickly into non-toxic form of HgS. Leaching of zinc from the catalyst (Zn-diethyl-dithiocarbamate) contained in the vulcanized sorbents is negligible at neutral pH conditions and small (about 10 %) at acidic conditions (pH = 1.5).n
