چکیده

This article uses produced nanoparticles and a UV lamp to study the photocatalytic degradation process of the malachite green dye... sol-gel precipitation route was used to create the chromium oxide nanoparticles. The first part includes the preparation of chromium oxide nanoparticles using the sol-gel precipitation route. X-ray diffraction (XRD) was used to investigate the properties of nanocomposite materials. The particle size of synthesized chromium oxide nanoparticles was determined using the Scherer equation. Dye degradation was conducted in irradiated aqueous suspension solutions, utilizing 0.17 g/100 ml of nanocomposite, with varying dye concentrations. The impact of nanocomposite mass, Malachite-green-dye concentration and temperature on the photocatalytic degradation of Malachite-green dye was investigated. The calculated activation energy is 38.61 kJ.mol-1. The irradiation solutions were examined using a UV-Vis spectrophotometer.
