Effects of activating agent and pyrolysis temperature on the pore structure and adsorption performance of sweet potato vine-based activated carbon

Key Points

• To evaluate how the activating agent and pyrolysis temperature affect the pore structure and adsorption ability of activated carbon from sweet potato vines.
• Analyzed different activating agents used in the production of carbon.
• Adjusted pyrolysis temperatures during carbon preparation.
• Conducted adsorption tests to measure performance with methylene blue.
• Activated carbon displayed a high surface area.
• Adsorption capacity for methylene blue was significantly influenced by temperature.
• Electrostatic interactions and hydrophobic interactions were key in adsorption effectiveness.
