Abstract: In this research, carbon dot was synthesized from a plastic waste materials. The prepared carbon dots was investigated for its reaction, structure, morphology and remediation of Fe3+ in industrial wastewater. The carbon dots (CDs) were characterized using the UV-Visible spectrophotometry, Fourier Transform Infrared Spectrophotometry (FTIR), Energy Dispersive Spectrometry (EDX), Powdered X-ray Diffractometry (PXRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). UV-Visible spectra revealed that carbon dot showed maximum absorption peaks at 286nm. FTIR results of carbon dot showed reactive functional group –OH, ClO, C=O and C–O. The EDX results revealed the elemental composition with percentages of the elements in the materials. The SEM morphology of the synthesized carbon dot was spherical in shape. The average particle size of the nano-dot as characterized by TEM was 3.94nm. XRD spectra results showed that the carbon dot is an amorphose substance. Adsorption studies was carried out using the carbon dot to remediate Fe3+ from wastewater. Result showed that the carbon dot reduced the concentration of Fe3+ in the wastewater considering the parameters of contact time and adsorbent dosage.
