Polyrhodanine modified anodic aluminum oxide membrane for heavy metal ions removal

Electrokinetic and antibacterial properties of needle like‐TiO2/polyrhodanine core/shell hybrid nanostructures

“…Jooyoung et al, also reported similar EDX mapping for PRh in a study carried out with PRh modified anodic aluminum oxide membrane. 37 TEM image of TiO 2 particles showed needle like and agglomerated morphology [ Figure 7(a)], provided by Nanostructured and Amorphous Materials). TEM image of needle like-TiO 2 / PRh nanocomposite [ Figure 7(b)] revealed that surfaces of needle like-TiO 2 particles were covered with thin layer of PRh shells homogeneously, with a shell thickness ranging between 4.8 and 6.5 nm, and composed a core/shell structure which held by electrostatic interactions.…”

Synthesis and characterization of nanocomposite NiFe2O4@SalenSi and its application in efficient removal of Ni(II) from aqueous solution

“…Several conventional methodologies such as precipitation [4], ion exchange [5], filtration membrane technology [6], electrochemical processes [7] and adsorption process [8] are available for heavy metal removal and other pollutants from wastewaters. Generally, they are expensive or ineffective sometimes, especially when the metal concentration is higher than 100 mg/L [9].…”

Synthesis of poly(amidoamine)-graft-poly(methyl acrylate) magnetic nanocomposite for removal of lead contaminant from aqueous media

“…Nowadays, numerous well-known methods such as chemical precipitation (Pang et al 2011), membrane filtration (Song et al 2011), ion exchange (Wdjtowicz and Stokmosa 2002), electrochemical treatment technologies (Belkacem et al 2008) and adsorption (Jiang et al 2015;Ghaffari et al 2015;Tan et al 2012;Mahmoud et al 2013) have been extensively explored for the removal and extraction of heavy metals from water/wastewater media. Among these water treatment methods, adsorption is one of the most effective and economic routes that have been widely used for removal of heavy metals.…”
