Study on the adsorption of Cu(Ⅱ) and Pb(Ⅱ) in water by carbon nanotube-loaded biochar

Key Points

• Heavy metals like Cu(Ⅱ) and Pb(Ⅱ) can be effectively adsorbed by carbon nanotube-loaded biochar, enhancing purification.
• The adsorption capacity significantly increases when using carbon nanotubes alongside biochar, improving heavy metal capture.
• Assessment through direct tests shows higher efficiency in removing both Cu(Ⅱ) and Pb(Ⅱ), achieving substantial reductions.
• This method highlights a promising avenue for developing cost-effective water treatment solutions to combat heavy metal contamination.
