    • The impact of biochar's physicochemical properties on sorption of perfluorooctanoic acid (PFOA) 

      Skjennum, Karen Ane Frøyland; Krahn, Katinka Muri; Sørmo, Erlend; Wolf, Raoul; Goranov, Aleksandar I.; Hatcher, Patrick G.; Hartnik, Thomas; Arp, Hans Peter Heinrich; Zimmerman, Andrew R.; Zhang, Yaxin; Cornelissen, Gerard (Peer reviewed; Journal article, 2024)
      To better characterize properties governing the sorption of per- and polyfluoroalkyl substances (PFAS) to biochar, twenty-three diverse biochars were characterized and evaluated as sorbents for perfluorooctanoic acid (PFOA). ...

    • Sewage sludge biochars as effective PFAS-sorbents 

      Krahn, Kathinka M.; Cornelissen, Gerard; Castro, Gabriela; Arp, Hans Peter; Asimakopoulos, Alexandros; Wolf, Raoul; Holmstad, Rune; Zimmerman, Andrew R.; Sørmo, Erlend (Peer reviewed; Journal article, 2022)
      The use of sewage sludge to produce biochar-based sorbents for per- and polyfluoroalkyl substances (PFAS) removal from water and soil may be an economically and environmentally sustainable waste management option. This ...
