Metal ion adsorption using polyamine-functionalized mesoporous materials prepared from bromopropyl-functionalized mesoporous silica

An Overview of Applying Surfactants to Modified-Functionalized Nanoporous Materials for Metal Ions Sequestration

“…Alothman and Apblett [31] studied the capability of mesoporous silica functionalized with di-, tri-, or penta-amine groups for Cu(II), Zn(II), and Cd(II) ions sequestration from aqueous solutions. Experimental results revealed that all amines exhibited high potential for removal the metal ions in similar tendency of Cu(II)>Zn(II)>Cd(II).…”

Construction of a New Sensor with Ruthenium Complex Anchored in Functionalized Silica and Their Application in Determination of Ascorbic Acid in Industrial Fruit Juice

“…The advantages of the use of organofunctionalized silica, containing on its surface the sequestering agent for transition metals are related to their high thermal stability, the accessibility of reactive centers and its insolubility in organic means [8,9].…”

Adsorption characteristics of mesoporous silica SBA-15 synthesized from mine tailing

“…Mesoporous silicas with high surface have found applications in various fields, such as catalysts, sensors and adsorbents (Aguado et al, 2009;Alothman and Apblett, 2010;Kim et al, 2011Kim et al, , 2014Li et al, 2011;Machida et al, 2012;Majchrzak-Kucęba and Nowak, 2011). Among mesoporous silicas, SBA-15 has drawn considerable attention as an absorbent for metals due to its high specific surface area, N800 m 2 /g (Aguado et al, 2009;Kim et al, 2011).…”

“…At present, the reported amount of accumulated mine tailings is around 88 million tons and the estimated number of abandoned mines is approximately 1000 in Korea. Furthermore, it has been of great concern about the heavy metals present in the mine tailings, because these metals are the primary cause of contamination of any nearby water system, which in turn affects agricultural crops and threatens human life (Ahn et al, 2011;Alothman and Apblett, 2010;Ercikdi et al, 2009;Huang and Hu, 2008;Kim et al, 2011;Li et al, 2010aLi et al, , 2011Machida et al, 2012;Shi et al, 2009).…”
