Description
Carbon nanoparticles from Polyethylene Terephthalate (PET) bottles has attracted good attention owing to their exceptional properties such as wide surface area, lower cost, biocompatibility, cytotoxicity, catalytic properties, drug delivery and biosensing. The processed carbon nanoparticles from PET bottles, using hydrothermal method possesses an excellent adsorption quality for the removal of Fe (III) from waste water. The characteristics of the carbon nanoparticles were revealed using Fourier Transform Infrared Spectrometer (FTIR), Energy Dispersive Spectrometer (EDX), X-ray Diffractrometry (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The adsorption of Fe (III) from the waste water increases with increase in contact time (15min – 2 h) and dosage (0.1g - 0.8g). The characterization and application results showed that carbon nanoparticles from PET bottles synthesized by hydrothermal methods, possesses good surface chemistry that promote effective adsorption of Fe (III) from waste water. This makes PET bottles a viable material for the synthesis of carbon nanoparticles for heavy metals removal from waste water.
