Green Synthesis of Zinc Oxide Nanoparticles using Allium sativum Plant Extract and Photocatalytic Activity of Rhodamine B

Abstract

The green approach is regarded as an economical and environmentally responsible way to create nanoparticles. In the field of dye degradation, the photocatalytic degradation mediated by nanoparticles is an effective method. Rhodamine B is a dye that, even at very low concentrations, is highly mutagenic and carcinogenic. Prior to discharge, Rhodamine B must be removed from wastewater. A low-cost plant employed in the manufacture of zinc oxide nanoparticles is Allium sativum. By using XRD and SEM, the synthesized nanoparticles were identified. Rhodamine B was eliminated using zinc oxide nanoparticles. The results demonstrated 99.99% Rhodamine B decolorization at reaction rates of 0.028 mg/L/min for 180 min at 5 ppm dye concentration, 1 g/L catalyst concentration, and pH 6. Analysis using FTIR, HPTLC and UV-Visible spectrophotometers proved Rhodamine degradation. Vigna radiata L, a key agricultural plant, was used to test the toxicity of Rhodamine B and treated effluent. The findings supported the treated effluent’s lower toxicity than the original chemical by showing that the plant and soil had a less harmful reaction to being irrigated with treated water.
