Adsorption of Lead from Effluents Using Synthesized ZnO Nanoparticles: A Comprehensive Study for Wastewater Treatment

Abstract

Water is essential for maintaining life, making up about 60% of the human body. Sadly, water pollution brought on by different industrial processes and human activities seriously jeopardizes our health. The degradation of water quality, which results in lower oxygen levels, is caused by the release of organic and inorganic compounds, pathogens, herbicides, pesticides, medicines, heavy metals, and visual contaminants into water bodies. Heavy metals are among these contaminants that are of special concern to the environment because of their toxicity and bioaccumulative characteristics. The amazing capacity of the adsorption technique to eliminate hazardous metals has attracted the attention of researchers. Through physicochemical interactions, adsorbates are bound to the solid surface of adsorbents using this technique. To eliminate lead from contaminated water, ZnO nanoparticles will create in the current work utilizing the coprecipitation technique for synthesis. To examine the synthesized nanoparticles, number of analytical methods will use, such as UV-Visible spectrum and SEM (Scanning Electron Microscopy). Atomic Absorption Spectrophotometry will also be used to measure the amount of lead removed both before and after the adsorption process. Important factors like pH, dose, and contact time will strictly regulate throughout our research. To confirm the veracity of findings, Kinetic Models will apply. Ultimate goal of this research is to increase the effectiveness of heavy metal removal and offer useful information regarding the usage of chemically produced ZnO nanoparticles for water filtration. This research project has the potential to make a substantial contribution to improving environmental management procedures and protecting our water resources.
