A New Method for Mercury Removal
Biotechnology Letters, 2005 A method is described for the removal of mercury from solution by using the off-gas produced from aerobic cultures of Klebsiella pneumoniae M426. Cells growing in Hg-supplemented medium produced a black precipitate containing mercury and sulphur. The ratio of Hg:S was determined as approximately 1:1 by analysis using proton-induced X-ray emission ...

Chitosan for removal of mercury from water
, 1984 Chitosan from prawn waste was used for the removal of mercury from solutions. Mercuric chloride solutions containing 250, 500, 1000, 10000 and 100000 ng of Hg super(+2)/ml were treated with chitosan samples of different particle size for different periods.

Biomodification of Coal to Remove Mercury
Applied Biochemistry and Biotechnology, 1996A biological process for removal of mercury from coal is under investigation. Iron and sulfur oxidizing bacteria have previously been used for desulfurization of coal and for mineral mining. We have shown that removal of mercury from coal is also possible via the same principles.

Removal of mercury by adsorption: a review
Environmental Science and Pollution Research, 2015Due to natural and production activities, mercury contamination has become one of the major environmental problems over the world. Mercury contamination is a serious threat to human health. Among the existing technologies available for mercury pollution control, the adsorption process can get excellent separation effects and has been further studied ...

Bacterial removal of mercury from sewage
Biotechnology and Bioengineering, 1984AbstractMercury‐resistant bacteria, which are able to reduce mercuric ion (Hg2+) to metallic mercury (Hg0), were examined for their ability to remove mercury from waste‐water aerobically. Growth studies in artificial medium indicated that mercury increases the lag phase, but does not effect the growth rate of these bacteria.

Mercury uptake and removal by Euglena gracilis
Archives of Microbiology, 2000The uptake and removal of mercury (added as HgCl2) from the culture medium by Euglena gracilis was studied. In cultures initiated in the light, cells accumulated a small fraction of the added heavy metal (5-13%). Mercury was both biologically and nonbiologically volatilized, and cell growth was partially inhibited; under these conditions the ...

Modeling Mercury Removal by Sorbent Injection
Journal of the Air & Waste Management Association, 1999Sorbents for removing mercury from flue gases of coal-fired power plants are presently being evaluated due to potential regulation of mercury emissions under Title III of the 1990 Clean Air Act Amendments. Laboratory tests have been conducted to evaluate the adsorption characteristics of potential sorbents and the effects of flue gas constituents on ...

The removal of mercury by gold surfaces, and the prevention of mercury photosensitization
Journal of Physics E: Scientific Instruments, 1970The removal of mercury vapour from gases by exposure to gold surfaces is investigated. Under suitable conditions, which are indicated, this technique can be used to virtually eliminate mercury photosensitization.
