| 摘 要： | Transition metal iron and persistent free radicals(PFRs) both affect the redox properties of biochar, but the electron transfer relationship between them and the coupling reduction mechanism of Cr(Ⅵ) requires further investigation. To untangle the interplay between iron and PFRs in biochar and the infuences on redox properties, FeCl3-modified rice husk biochar(FBCs) was prepared and its reduction mechanism for Cr(Ⅵ) without light was evaluated. The FBCs had higher surface positive cha...
