Preparation of ZnCl₂-Activated Magnetic Biochar and Its Performance in Removing Hexavalent Chromium from Water

Magnetic biochar (Zn/Fe-BC) was prepared from jujube branches via an impregnation pyrolysis–coprecipitation technique to eliminate Cr(VI) from water. ZnFe₂O₄ was introduced through ZnCl₂-based impregnation and pyrolysis, which can...
