文摘
- •
Synthesis of strongly magnetic biochar via oxidative hydrolysis of FeCl2.
- •
Saturation magnetisation of magnetic pine sawdust biochar (MPSB) is 47.8 A m2/kg.
- •
Single-phase iron oxide (Fe3O4) nanoparticles formed on the surface of biochar.
- •
Adsorption behaviour and regeneration were investigated.
- •
Sorption of sulfamethoxazole onto MPSB could be due to hydrophobic interaction.
