Innovative ferrite/beta-cyclodextrin core-shell nanocomposites for removal of inorganic and organic pollutants from aqueous effluents



Due to diversity of industrial and agricultural actvities, anything can come across in the polluted aqueous effluents like: heavy metals, dyes (since the invention of synthetic dyes 8000 of these compounds have been discoverd and used in the industry), phenols, detergents, pesticides PCBs etc. Oxidation processes cannot be effective in the purification of a large part of industrial effluents and, even were applicable, the energy consumption could be prohibitive from the economic point of view. 



In order to eliminate the problem related with separation step which represent the major drawback in the use of nanoparticles, this project propose a new water treatment technology based on nanoadsorbents with magnetic core (ferrite) and β-cyclodextrin shell for waste water treatment loaded with inorganic (heavy metals, nitrates, etc.) and organic (pesticides, dyes, phenolic compounds, etc.) compounds.

   A significant part of pollutants escape the current treatment methods and reach surface and ground waters. Therefore, in spite of great success in treatment of water and wastewater, the existing bottlenecks (high costs to obtain adsorbents, diffusion limitation which hinder the process, large amount of solid waste after use) limits the application of adsorption processes. In order to improve the process performance, a new approach is required.  In this context many, literature data shows that nanotechnologies can be harnessed to solve critical development problems, including wastewater pollution.
