Manganese removal from aqueous media using polyaniline nanocomposite coated on wood sawdust

Untitled

“…Another alternative material for adsorption of metals are the residues of the wood industry (sawdust) which are widely available, and often considered as waste (Qomi et al, 2014 (Vásquez-Guerrero et al, 2016); the percentage of the composition of the structure is directly related to the species of wood from which the sawdust is produced . The physio-chemical properties of the previously mentioned adsorbent, affect its removal capacity (Martín-Lara et al, 2016).…”

“…Otra alternativa como material para adsorción de metales son los residuos de la industria de la madera (aserrín) ampliamente disponibles, y a menudo considerados como desecho (Qomi et al, 2014) -Guerrero et al, 2016); el porcentaje de la composición de la estructura está en función de la especie de madera de donde provenga el aserrín .…”

“…Una opción es la adsorción, la cual es un proceso de transferencia de masa mediante el cual una sustancia pasa de la fase líquida a la superficie de un sólido, resultado de la afinidad entre los sitios activos del adsorbente con el adsorbato, unidos por interacción física y/o química, que puede llevarse a cabo por complejación, coordinación, quelación e intercambio iónico (Pehlivan et al, 2008). Además, la capacidad de adsorción está afectada por las propiedades del adsorbente como son área específica y química de la superficie (Qomi et al, 2014). En la actualidad, la adsorción es considerada una opción efectiva, económica y selectiva para el tratamiento de aguas (De Gisi et al, 2016).…”

Positron annihilation study on polyaniline nanocomposite used for Pb(II) ion removal

“…(2016) [1][2][3][4][5][6][7][8][9][10][11][12] www.deswater.com doi: 10.1080/19443994.2016.1167128 polymer composites and nanocomposites have drawn significant interest from the research community in recent years and are successfully used as adsorbents for heavy metals [2,3]. There have been numerous attempts reported on the adsorption of metal ions by functionalised polymers based on amine derivatives, such as polyacrylonitrile fibres, ethylenediamine and polyacrylamides [4][5][6].…”

“…To overcome this problem, various efforts have been made, such as the addition of side groups to the polymer backbone [12], polymer grafting to a non-conducting polymer [13], composites of conducting polymers [14] and copolymerisation [15,16]. In the recent years novel use of agricultural waste such as rice husk ash, wood sawdust and wheat straw have been successfully made to adsorb dyes and dye mixtures from effluent of textile industries [3,[17][18][19][20]. Among the various cellulosic materials that have been studied, sawdust is commonly used as an adsorbent for heavy metal ions being agricultural by products with no economical values [21,22].…”
