The Department of Chemistry is Holding a Seminar Discussion on a Study on the Photocatalytic Degradation of the Textile Dye Nigrosin Using an Environmentally Friendly Method

Seminar Discussion

Among the scientific activities taking place in the Department of Chemistry, a seminar entitled (A study on the Photocatalytic Degradation of the Textile Dye Nigrosin Using an Environmentally Friendly Method) was held. By the student (Hadeel Ahmed Kazem), under the supervision of Professor Dr. (Hamida Eidan Salman).
The aim of this seminar was to study the application of Agl-doped Sno nanoparticles in the photocatalytic decomposition of nigrosin dye. The Agl-Sno nanoparticle complex was prepared using the hydrothermal method.
It was also studied using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), and field emission scanning electron microscopy (FESEM). The photocatalytic activity of the Agl-Sno composite was evaluated under UV-A light, where it showed high efficiency in degrading nigrosin dye in aqueous solution. It was observed that the presence of methanol reduced the efficiency of photodegradation, while the addition of hydrogen peroxide enhanced the efficiency of the process. In the end, the nanocomposite achieved a high rate of dye removal within 120 minutes under visible light. We wish the student more success and excellence to complete her scientific career.
