Removal of Heavy Metals by Adsorption Using Magnetite Nanoparticles Coated Sand

Abstract

As we know that day by day pollution is increasing in our surroundings, Lethal substantial metal particles get acquainted with the sea-going streams by methods for different industrial exercises viz. pharmaceutical, mining, refining metals, manure ventures, tanneries, batteries, paper enterprises, pesticides and so forth and have a genuine danger to human beings and environment. In this thesis study we focuses on the removal of heavy metal (chromium) from the wastewater stream of the industries (pharmaceutical) by Adsorption using magnetite coated sand. So in this study we saw the removal efficiency of the heavy metal ion with the suitable amount of adsorbent dosage and also the affects of contact time on the removal efficiency of the heavy metal ion. At last we learn about the Freundlich and Langmuir isotherm. And also find the constants for them.
