Solar light induced photodegradation of brilliant green dye by barium calciate (BaCaO2) nanoparticles

Abstract

The study on photodegradation of Brilliant Green dye was done by barium calciate nanoparticles (BaCaO2). The BaCaO2 was prepared by solution combustion synthesis. The analytical instruments like SEM, XRD, EDAX, and UV-absorption spectroscopy were employed for characterization. All the experiments were accomplished under various irradiation conditions such as sunlight, UV light and dark conditions. The obtained results examined the percentage of degradation capacity of BaCaO2 on Brilliant Green by differing the Brilliant Green concentration, pH and catalyst loading. The percentage of degradation was 98.93% in 20ppm of dye concentration at pH 6 with a constant catalyst concentration of 0.7g/100mL. This proves that the synthesized barium calciate nanoparticles are more efficient in removing Brilliant Green from the wastewater.
