文摘
- •
Biochars varied in physicochemical properties and adsorption capacity.
- •
Canna indica derived biochar has a high sorption capacity for Cd2 +.
- •
NH4+ and Cd2 + sorption on biochars fits a pseudo second order and Langmuir model.
- •
Sorption mechanism is related to complexation, cation exchange and precipitation.
