Novel carbon material for highly efficient waste water treatment and procedures thereof

摘要

The present invention relates to a process for preparing porous carbon nanoparticles from crude carbon for treatment of waste water. The process comprises heating the crude carbon in a furnace at a first predefined temperature for a first predefined duration. The crude carbon is carbon waste obtained from carbon ink based devices, such as a photocopier or a printer. The method further comprises washing the heated carbon with an organic solvent and re-heating the washed carbon at a second predefined temperature for a second predefined duration to prepare the porous carbon nanoparticles.
