Removal of Copper (Cu) from Waste Water using Nanoparticles Submitted byPriyanka Takhar Prashant Gautam Vaibhav Gehlot 2010CEV2926 2014CEV2925 2010CH70189 » Introduction High demand of water due to increase in population High amount of wastewater is generated The wastewater contains micro-organisms, organics, metals and toxicants Metals (copper here) are highly carcinogenic Metals cannot be decomposed or bio-degraded They have to be removed during treatment » Removal of copper Precipitation Flotation Ion Exchange Electrocoagulation Adsorption Adsorption is widely used for the removal of metals because of its simplicity and effective cost » Nanoparticles The most common adsorbent (nowadays) are nanoparticles Nanoparticles are particles with size less than 100nm The advantages of using nanoparticles as adsorbent are High surface area in low volume Magnetic characteristics Low cost Effective contaminant removal even at low concentrations Less waste generation post-treatment Table 3: Comparison between different nano particles Source Palanisamy et al., 2013 Nano particle Magnetic iron oxide pH Time taken Removal (min) (%) 2.5 60 95.5 2.5 60 91.6 stabilized by Olive Oil Magnetic iron oxide stabilized by MIONs Flaxseed Oil Kana et al., 2013 Chitosan Nano-Particles - 30 100 Liu et al., 2008 Fe3O4 Magnetic 6.4 15 99.7 9.2 4380 99 2.5 120 81 Nanoparticles With Humic Acid Sukopová et al., 2013 Zerovalent Iron Nanoparticles Predescu et.al., 2012 Maghemite Nanoparticles Bhargav et al., 2013 Iron (III) Oxide 8 1710 100 7 120 98 5 90 97.6 3 90 98.21 5.5 30 98 Nanoparticle Xin et al., 2012 Amine-functionalized mesoporous Fe3O4 nanoparticles Rafiq et al., 2014 Zinc oxide nanoadsorbents Magnesium oxide nano-adsorbents Pang et al., 2011 Magnetic Nanoparticle » Limitations Corrosion of metal surface Reaction by-products » Future research Non corrosive nanoparticles should be more used Reaction by-products should be minimised » REFRENCES: Andra PREDESCU, Avram NICOLAE, 2012, “ADSORPTION OF ZN, CU AND CD FROM WASTE WATERS BY MEANS OF MAGHEMITE NANOPARTICLES”, U.P.B.
