Application of hardwood biochar as a reactive capping mat to stabilize mercury derived from contaminated floodplain soil and riverbank sediments
Wang, Alana O.; Ptacek, Carol J.; Blowes, David W.; Gibson, Blair Donald; Landis, Richard C.; Dyer, James A.; Ma, Jing (Elsevier, 2019-02-20)Hardwood biochar (pyrolyzed at 700 °C), a potential candidate for Hg removal, has been proposed for use as reactive capping mats along groundwater discharge zones or riverbanks to control release of Hg from contaminated ... -
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 ...
