Removal of contaminants from waste water by using Murrayakoenigii nanoparticles

Abstract

Today nanoparticles and nanocomposite are used for removal of metals and biological substances. Magnetic oxide nanoparticles are a class of engineered materials with very small size and which can be operated under the influence of external magnetic field. This is mainly due to their very efficient contaminant removal capacity, fast reaction rate and most importantly due to magnetic properties which enables its easy recovery. These magnetic nanoparticles are commonly synthesized by different methods. These preparation methods have several limitations in terms of operating cost production rates and risk to the environment and humans. In addition to these, magnetic nanoparticles lose their reaction rate due to macromolecules formation and magnetic property and dispensability on exposure of atmosphere. Green synthesis of magnetic nanoparticles has remained a comparatively new research area. The problem of treating waste water is being very severe, particularly in developing countries with disposal of untreated waste water. The release of untreated waste water with nutrients and metal concentration leads to worldwide ecological problem in water bodies. The present study revealed Murrayakoenigii (curry leaves) used for producing magnetic nanoparticles in green synthesis method and these magnetic nanoparticles have the potential to remove nutrients like Phosphate ion and Nitrate ion from wastewater and magnetic nanoparticles were characterised by FTIR,XRD and SEM Techniques.
