چکیده
Excessive use and discharge of organic pollutants inevitably lead to their accumulation in the environment and bring considerable environmental risks. Innovative methods based on nanotechnology for wastewater treatment processes have been increasing in recent years. In this work, cobalt oxide (Co3O4) nanoparticles have been synthesized via a green and simple route and used as the effective photocatalyst for the degradation of bromocresol green. Approximately 88% of bromocresol green was degraded in the presence Co3O4 nanoparticles after 5 hours under sunlight. The kinetic studies showed that photocatalytic degradation process followed the pseudo-first-order kinetic model. The photocatalytic performance of Co3O4 nanoparticles was evaluated for the treatment of natural wastewater, and the obtained results showed that this system could remove 78% of organic dye within 5 hours. The promising points for this study were the easy operation, simple equipment, good catalytic performance, cleaner reaction profile and environmentally friendly reaction conditions. The obtained results showed that Co3O4 nanoparticles were an efficient catalyst that could be employed for the photodegradation of different types of organic pollutants.
