Study of agglomeration and magnetic sedimentation of Glutathione@Fe3O4 nanoparticles in water medium

The study of the efficiency of the magnetic separation of nanoparticles in environment is important for its implementation in the remediation of water bodies. In this work the sedimentation dynamics of Glutathione@MNPs were evaluated for water systems with addition of calcium, zinc and sodium ions i...

En este trabajo se evaluó la dinámica de sedimentación de los Glutatión@MNPs en sistemas de agua con adición de iones de calcio, zinc y sodio en un rango de concentración de 0-40 mg/L en presencia y ausencia de un campo magnético vertical de 0,2 T. Las concentraciones críticas de coagulación (CCC) se determinaron basándose en la teoría de DLVO. Se observó estabilidad de la partícula en ausencia de iones metálicos mayores de 8 semanas, mientras que con la presencia de estos iones la estabilidad se redujo a 8 semanas. La separación del material de la fase acuosa superior al 90% se obtuvo tanto para la presencia de iones como para el material después de la adición de metales pesados tales como Hg y Cr.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Minashttps://revistas.unal.edu.co/index.php/dyna/article/view/68245Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaBolívar, Wilfredo Marimón and Gonzalez, Edgar E.
