Photocatalytic removal of polychlorinated biphenyls (PCBs) using carbon-modified titanium oxide nanoparticles

- Carbon-modified (CM)-n-TiO2 nanoparticles were synthesized via a sonicated sol-gel method.
- Photocatalytic removal of PCBs from aqueous solution was investigated using CM-n-TiO2.
- Carbon modification enhanced the photocatalytic activity of CM-n-TiO2.
- The highest removal rate was obtained at pH 5 and catalyst dose of 0.5 g L−1.
- Photocatalytic removal data were successfully fitted using Langmuir-Hinshelwood model.
