Fabrication of poly(methyl methacrylate)/silica KIT-6 nanocomposites via in situ polymerization approach and their application for removal of Cu²⁺ from aqueous solution

Abstract

Novel mesoporous silica nanocomposites for adsorption of Cu(ii) from aqueous solution were prepared by in situ polymerization of MMA and modified KIT-6 as filler.

A novel porous nanocomposite of aminated silica MCM‐41 and nylon‐6: Isotherm, kinetic, and thermodynamic studies on adsorption of Cu(II) and Cd(II)

“…13,14 As an important family of adsorbents, polymer matrix nanocomposites (PMNCs) including organic (polymer Matrix) and inorganic moieties (filler) have attracted increasing attention among the other conventional adsorbents. 17,18 These NCs showed an excellent removal performance in batch adsorption experiments. [15][16][17][18] Recently, nanostructured porous silica materials such as SBA-15, KIT-6, MCM-41, MCM-48 have consistently been of interest in polymer science and technology.…”

“…6,7 Cadmium reaches these organs (kidney, liver, lung, and skin) in form of cadmium-metallothionein. [15][16][17][18] Recently, nanostructured porous silica materials such as SBA-15, KIT-6, MCM-41, MCM-48 have consistently been of interest in polymer science and technology. 8 Consequently, when cadmium enters the blood circulation, it usually forms cadmiumcysteine complexes and causes health problems like cancer.…”

Multifunctions of Polymer Nanocomposites: Environmental Remediation, Electromagnetic Interference Shielding, And Sensing Applications

“…[55] Nanoparticles such as semiconductive materials (i. e. TiO 2 , ZnO, WO 3 ), zero-valence metal (i. e. Fe, Cu, Zn), bimetallic nanoparticles (Fe/Ni, Fe/Pd) play a key role in environmental remediation given their high interfacial reactivity with contaminants such as nitroaromatics, dyes, halogenated aliphatics, heavy metals. Poly(methyl methacrylate), [57] poly(vinylidene fluoride), [58] polysulfone, [59] polyvinyl pyrrolidone, [60] polyamine, [61] polyacrylamide [62] and polyethylenimine, [63] etc. To facilitate the separation and reuse as well as to prevent the release of these nanoparticles into the ecosystem which might impose risk to the health of human beings, a mostly used strategy is to impregnate or coat the nanoparticles onto a host.…”

Preparation and characterization of starch nanocomposite embedded with functionalized MWCNT: Investigation of optical, morphological, thermal, and copper ions adsorption properties

“…[31] In this study, prepared NC was used to examine its adsorption performance for the removal of copper ions from the aqueous solution. So it is indispensable to eliminate them from aqueous solutions.…”
