Control of mercury and methylmercury in contaminated sediments using biochars: A long-term microcosm study

Liu, Peng; Ptacek, Carol J.; Blowes, David W.; Gould, W. Douglas (Elsevier, 2018-05-01)

The effectiveness of activated carbon and four types of biochar, switchgrass (300 °C and 600 °C), poultry manure (600 °C), and oak (∼700 °C) with respect to mercury (Hg) and methylmercury (MeHg) control was assessed in ...
