Green Synthesis of ZnO Nanoparticles Using Leaves Extract of Quisqualis Indica (Madhumalti): Textile Effluent Treatment and their WQI Study

Industrial effluents, which often contain harmful pollutants such as organic compounds, heavy metals, and toxic chemicals, pose a serious environmental threat. These wastes are frequently discharged into water bodies without adequate treatment, leading to severe water pollution that harms aquatic life, ecosystems, and human health. Nanotechnology presents an innovative and effective solution for water purification, particularly in treating industrial waste. Nanomaterials, due to their high surface area, reactivity, and adsorption capacity, are highly effective in removing contaminants like heavy metals and dyes. This study focuses on the green synthesis of zinc oxide (ZnO) nanoparticles using Quisqualis indica and evaluates their efficiency in purifying industrial wastewater. Standard protocols were followed for both the synthesis and analysis. The results were promising: after treating textile effluents with the synthesized ZnO nanoparticles, the water became odourless and clear, with significant reductions in turbidity, total dissolved solids (TDS), chloride levels, and conductivity. These findings suggest that ZnO nanoparticles synthesized via green methods can serve as efficient adsorbents for industrial effluent treatment.
