Use of Iron Nanoparticles to remove waterborne pathogens

Abstract

In recent sciences Nanotechnology is a burning field for the researchers. Nanotechnology deals with the Nanoparticles having a size of 1-100nm in one dimension used significantly concerning medical chemistry, atomic physics, and all other known fields. Nanoparticles are ultrafine materials with unique properties due to their small size and high surface area. These properties make them highly effective in a variety of applications, including water treatment. Waterborne pathogens are a major cause of water pollution, contributing to numerous public health issues worldwide. Contaminated water sources, such as rivers, ponds, and sewage systems, often harbour harmful microorganisms that pose significant risks to human health. Among the various types of nanoparticles, iron nanoparticles have shown considerable promise in the removal of waterborne pathogens. This approach involves the use of iron nanoparticles for the removal of waterborne pathogens was investigated in this study to assess their potential in water purification. Green synthesis of iron nanoparticles using nitric acid and ferric chloride was done. Water sample—sewage water—were collected for analysis. Total viable count (TVC) was performed on the untreated sample, and the sample were subsequently treated with iron nanoparticles to evaluate their pathogen removal efficacy. A filter was constructed incorporating the synthesized nanoparticle. The results demonstrated a significant reduction in microbial load in all water samples, indicating that the synthesized nanoparticles effectively aided in pathogen removal and can be considered as viable candidates for water purification applications.
