Nanoparticles for use in wastewater treatment

Water plays pivotal role in life. Problems occur when human being and wildlife do not have access to fresh water. In modern day society, with the advancement of technology, it is important to improve the quality of water. There are innumerable methods used for the treatment of wastewater, such as conventional adsorption, flocculation, filtration—although these are only used for primary wastewater treatment—along with physical, biological, chemical, and mixed treatment methods.. In order to overcome all these issues with conventional methods, we have developed Fe nanoparticles by adding FeCl₃ 0.1 M solution to plant extracts and LDS nano catalysts fvia the co-precipitation method through the addition of MI and MII metals with the addition of a base. Nanotechnology is evolving in allareas of science and engineering; our main objective is to evaluate the application of Fe NPs and layered double hydroxides (LDHs nano particles, which were characterized by SEM analysis for determining morphology. A 15–13mm spherical shape was formed. The FTIR results at 3272 and 1000 cm⁻¹ were to the presence of several biomolecules during the formation of Fe NPs, and we successfully removed MB and MO from water. Fe NP and LDH nanomaterials show promise in future use for the treatment of wastewater and in many industries at a global level.
