| Abstract Scope |
With the growth in various industries, such as metal cleaning, electroplating, pigment, mining and leather processing, heavy metals (Cr, Cd, Hg, Pd and As) have become a widespread pollutant in the surface water and groundwater. Recently, magnetic carbon nanocomposites with large specific surface area were introduced to remove the heavy metal in the wastewater and displayed the excellent efficiency. Here, we successfully synthesized the novel nitrogen doped carbon composites with higher magnetism and specific surface areas using waste plastic as carbon and nitrogen source through simple method. After that, we utilized the as-synthsized materials to treat the Cr(VI) solution, and found that the excellent performance were observed (removal capacity: 12.1 mg/g, PH at 7; 400 mg/g, PH at 2), which indicating nitrogen doped magnetic carbon nanocomposites are the promising materials for the environmental remediation. |
