Industrialization has revolutionized the quality of life but also led to the increase in environmental pollution in the form of industrial waste. The effluents released from the industries include toxic compounds which get accumulated in soil and persist for years if not treated properly. These persisting, nondegradable compounds include the heavy metals which are mostly released into the soil from electronic industries in the form of E-waste. Electronic industries are the fast growing industries and the amount of the waste released from them is considerably high. Most of the electronic goods are made of heavy metals like Lead (Pb), Cadmium (Cd), Zinc (Zn), etc., of which Lead is an important metal found in most of the electronic goods which is highly toxic. The metal leaches into the soil if not processed properly and leads to contamination of soil thereby affecting the lives of flora and fauna on earth. To prevent this the present study focused on the use of nanotechnology in the removal of Lead from contaminated soils. Magnetite nanoparticles are used for Lead adsorption. The unique property of high affinity of magnetite nanoparticles towards cations enables a better adsorption of Lead by the nanoparticles.The current study focuses on the application of Magnetite nanoparticles in reducing Lead toxicity by adsorption technique. The nanoparticles exhibited a higher rate of metal removal upto 2500ppm. X ray diffraction study revealed the size of the magnetite nanoparticle to be 4.3nm. The structure of the nanoparticle was determined by Scanning electron Microscope and Transmission electron microscope.Index Terms-Magnetite nanoparticles, metal adsorption, and adsorption isotherm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
