PREPARATION AND CHARACTERIZATION OF BIOSORBENTS BASED ON MWCNT-MAGNETITE-HYDROXYAPATITE COMPOSITES AND ITS POTENTIAL APPLICATION IN THE REMOVAL OF HEAVY METALS

Descripción del Articulo

In the present study, new biosorbents based on magnetite (Fe3 O4 ), hydroxyapatite (HAp) and multiple-walled carbon nanotubes (MWCNT) composites were prepared. The materials were characterized by dynamic light scattering (DLS), infrared spectroscopy (FTIR), scanning electron microscopy (SEM), vibrat...

The materials were characterized by dynamic light scattering (DLS), infrared spectroscopy (FTIR), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), raman spectroscopy and square wave voltammetry (SWV). The synthesized magnetite presented a ferromagnetic behavior. HAp was smaller by hydrothermal synthesis. In addition, the possible use of the composite involving the 3 starting materials (Fe3O4/MWCNT/HAp) in the removal of a heavy metal such as As(V) in aqueous solution was evaluated, taking into account the influence of factors such as pH, adsorbent mass and contact time. The maximum values of percentage of removal of this metal (greater than 85 %) were obtained under conditions of pH 6, adsorbent dose of 0. 5 g L-1 and a contact time of 2 hours.En el presente estudio, se prepararon nuevos biosorbentes basados en compósitos de magnetita (Fe3 O4 ), hidroxiapatita (HAp) y nanotubos de carbono de pared múltiple (MWCNT). Los materiales preparados fueron caracterizados mediante técnicas de dispersión dinámica de luz (DLS) espectroscopía infrarroja (FTIR), microscopía electrónica de barrido (SEM), magnetometría de muestra vibrante (VSM), espectroscopía Raman y voltamperometría de onda cuadrada. La magnetita sintetizada presentó un comportamiento ferromagnético. La HAp tuvo menor tamaño mediante la síntesis hidrotermal. Además, se evaluó el posible uso del compósito que involucraba a los tres materiales de partida (Fe3 O4 /MWCNT/HAp) en la remoción de un metal pesado como As(V) en solución acuosa, teniendo en cuenta la influencia de factores como pH, masa de adsorbente y tiempo de contacto. Se obtuvo los valores máximos de porcentaje de remoción de este metal (mayor a 85 %) a condiciones de pH 6, dosis de adsorbente de 0,5 g L-1 y un tiempo de contacto de 2 h.Sociedad Química del Perú2019-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontexttextoapplication/pdfhttp://revistas.sqperu.org.pe/index.php/revistasqperu/article/view/26010.37761/rsqp.v85i4.260Revista de la Sociedad Química del Perú; Vol. 85 Núm. 4 (2019): Revista de la Sociedad Química del Perú; 463 - 475Journal of the Chemical Society of Peru; Vol. 85 No. 4 (2019): Journal of Sociedad Química del Perú; 463 - 4752309-87401810-634X10.37761/rsqp.v85i4reponame:Revista de la Sociedad Química del Perúinstname:Sociedad Química del Perúinstacron:SQPspahttp://revistas.sqperu.org.pe/index.php/revistasqperu/article/view/260/228Derechos de autor 2019 Sociedad Química del Perúhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:rsqp.revistas.sqperu.org.pe:article/2602020-04-09T05:09:42Z
