| description |
The development of magnetic nanoparticles by ACCVD is a powerful technique to synthesize material with high purity. The size and composition of magnetic nanoparticles was tailored, by variation of the flow ratio Ar-Air and furnace temperature. Different types of nanoparticles were obtained from metallic Fe until Fe2O3. The size of magnetic nanoparticles was between 195 nm and 272 nm. The synthesis temperature was between 440 and 590 oC. The nanoparticles were collected by using an impactor plate at 120 oC. The obtained materials were characterized by high resolution electron microscopy, X-ray diffraction and ICP-MS. These particles were used to remove arsenic from contaminated water. The magnetic nanoparticles showed a high capacity to adsorb arsenic. The initial concentration of arsenic in water was 20 ppbs and after remotion with hematite the arsenic disappeared from solution. To remove arsenic from solution the ultrasonic method was used to mix the magnetic nanoparticles with arsenic and subsequent precipitation with super magnets. |

El tamaño y composición de las nanopartículas magnéticas fue conseguido, por la variación en la relación de flujo de Ar- Aire, así como la temperatura del horno. Se obtuvieron diferentes tipos de nanopartículas desde Fe metálico hasta Fe2O3. El tamaño de las nanopartículas magnéticas estuvo entre 195 nm y 272 nm. La temperatura de síntesis varió de 440 a 590 oC y el método de recolección de las nanopartículas se realizó con una placa impactor plana a 120 oC. El material obtenido fue caracterizado por microscopia electrónica de alta resolución, ICP-MS y difracción de rayos X. Estas nanopartículas fueron usadas para remover arsénico de agua contaminada. Las nanopartículas magnéticas mostraron una alta capacidad para adsorber el arsénico. La concentración inicial de arsénico en agua fue de 20 ppbs y después de la remoción con la hematita el arsénico desapareció de la solución. Para remover el arsénico de la solución fue usado el método de ultrasonificación para mezclar las nanopartículas magnéticas con el arsénico y su posterior precipitación con super imanes.application/pdfspaUniversidad Nacional de Colombia, Bogotáhttp://revistas.unal.edu.co/index.php/momento/article/view/41554Universidad Nacional de Colombia Revistas electrónicas UN MOMENTO - Revista de FísicaMOMENTO - Revista de FísicaMOMENTO - Revista de Física; núm. 46 (2013); 28-37 0121-4470Barrientos, Eutiquio and Matutes, José and Miki, Mario (2013) Arsenic removal from water using magnetic nanoparticles obtained by accvd.
