| چکیده مقاله |
| Trends associated with industrial activities have affected sources of fresh water and human health. Herein, we have synthesized and characterized a Bi-based photocatalyst to treat a synthetic wastewater containing Acid Orange 7 (AO7) as pollutant. XRD and FTIR results revealed that synthesized powder are high-purity tetragonal-phase of BiOCl. Furthermore, DRS analysis demonstrated that the bandgap energy of synthesized is about 3.3eV, which is lower than the values reported in other studies. Subsequently, to investigate morphology and surface properties, FESEM and BET analysis were employed. The results showed that the powder are in plate-like shape which leads to higher surface area in comparison with other works and it confirmed effective photocatalyst performance. Moreover, due to BET test, the powder’s surface area was about 27.9 m2/g. In addition, photocatalytic performance of BiOCl were examined in different pH values. Obtained findings revealed that the BiOCl photocatalyst demonstrated more effective in acidic conditions which is reasonable due to mentioned photochemical reactions. Finally, toxicity assessment was employed and the results demonstrated that generated secondary wastewater was less toxic than initial wastewater. |
