RE-USABILITY STUDIES OF ADSORPTIVE REMOVAL OF SOME HEAVY METALS BY MAGNETITE NANOPARTICLES FROM AQUEOUS SOLUTION

Abstract

The ecosystem and public health and safety may be at risk if untreated industrial wastewater effluent is released into the natural environment. The rate of water-borne illnesses is extremely concerning, according to records that are currently available from many health centers in most developing countries. Elevated physicochemical and biological properties concentrations in industrial wastewater effluent have the potential to cause problems for the environment and public health (Dydo et al., 2005; Fujita et al., 2005). In light of this, treating wastewater effluent is crucial before releasing it into the environment. In light of this, wastewater effluent must be cleared of all biological and physico-chemical impurities before being released into the environment. The goal of this study is to compare the biological and physico-chemical characteristics of industrial wastewater effluent with the W.H.O. standard discharge limit. Furthermore, the study used a standard operating procedure and technology to remove the pollutants from the waste water by using magnetite nano-particles as an adsorbent. The aim of the study is to investigate the re-usability potential on the adsorptive removal of some heavy metals from Aqueous Solution by magnetite nanoparticles. The result shows the as the time progresses the removal percentage increases with decrease in the filtrations cycles across all the contaminants. The first cycle shows higher (p < 0.05) of efficiency of the contaminant removal with the last cycle having the least. The treated effluent was analyzed, and a substantial removal was achieved with 94.21%, 89.62%, 77.26%, and 74.39% at 250 minutes contact time, in the removal efficiencies of copper, zinc, turbidity and boron respectively.
