Ameliorating textile effluent phytotoxicity in Vigna radiate through biosynthesized Fe/Zn bimetallic nanoparticles: sustainable approach for environmental remediation
Discharging of untreated textile effluents, rich in toxic heavy metals, dyes, and other harmful pollutants, poses threats to aquatic ecosystems and agricultural quality and productivity. Nanotechnology being an emerging field, provides solutions for the remediation of the environment. However, this study examines the potential of bimetallic Fe/Zn NPs in treating textile effluent and their effect on the growth and biochemical parameters of Vigna radiata L. under effluent stress. The Fe/Zn NPs were novelly synthesized using Conocarpus erectus L. leaf extract, characterized by Ultraviolet–visible spectroscopy, X-Ray diffraction, Scanning electron microscopy, and Fourier-transform infrared spectroscopy and optimized at 0.5 mg mL−1 for effluent treatment and 50 ppm for Vigna radiata growth, outperforming other concentrations. The optimized Fe/Zn NPs dosage effectively treated the effluent, reducing total dissolved solids (40.4%), phosphate (85.9%), sulfate (87.8%), color intensity (92.8%), chemical oxygen demand (97.5%), and hexavalent chromium (95.6%). Additionally, the application of Fe/Zn NPs as nano fertilizers and treated effluent significantly improved growth (root and shoot length, weight), photosynthetic (chlorophyll a, b, total chlorophyll, and carotenoids), and antioxidant (superoxide dismutase, peroxidase, and catalase) levels, while reducing oxidative stress (hydrogen peroxidase and malondialdehyde) in Vigna radiata, compared to untreated textile effluent. These key findings suggested the application of bimetallic Fe/Zn NPs as an environment friendly and sustainable approach to mitigate the toxicity of textile effluent and offering a promising solution for environmental remediation and agriculture sustainability.
