Green preparation of shell-based biochar and its adsorption of multi-component chlorinated volatile organic compounds

Key Points

• The research aims to develop a sustainable method for producing biochar and assess its effectiveness in adsorbing pollutants.
• Utilized a green preparation method with sodium phytate and sodium hydroxide.
• Prepared biochar from various shell-based biomass wastes.
• Conducted adsorption tests on multi-component chlorinated volatile organic compounds.
• Demonstrated effective adsorption of chlorinated volatile organic compounds by the biochar.
• Highlighted the potential of using agricultural waste for environmental remediation.
