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 ... -
Evaluation of mercury stabilization mechanisms by sulfurized biochars determined using X-ray absorption spectroscopy
Liu, Peng; Ptacek, Carol J.; Elena, Krista M. A.; Blowes, David W.; Gould, W. Douglas; Finfrock, Y. Zou; Wang, Alana O.; Landis, Richard C. (Elsevier, 2018-04-05)The application of biochar to treat mercury (Hg) in the environment is being proposed on an increasing basis due to its widespread availability and cost effectiveness. However, the efficiency of Hg removal by biochars is ...
