Potential efficiency of magnetic mesoporous silica nanoparticles modified with aspartic acid to cationic dye removal from aqueous solution

Adsorption equilibrium and kinetics studies of crystal violet adsorbed by anionic polymer brush functionalized mesoporous silica nanoparticles

“…Surface functionalization with organic groups has been found to enhance the selectivity and adsorption capacity of MSNPs while preventing aggregation [40]. Various surfacefunctionalized mesoporous silica materials have been investigated for the adsorption of cationic, anionic, and heavy metal ions [41][42][43]. For example, chitosan-coated nanoparticles modified with diethylenetriamine pentaacetate have been synthesized to improve the selective adsorption of lead (II) and methylene blue (MB) [44].…”

Magnetic Mesoporous Silica Nanoparticles Functionalized with 5,5′-Dithiobis(2-Nitrobenzoic Acid) for Highly Efficient Removal of Organic Dyes from Contaminated Water

“…Te adsorption isotherm was ftted with the Freundlich model, and the kinetics of MB adsorption on MSN-Cys was found to ft a pseudo-second-order kinetic model, with an adsorption capacity of 140 mg/g [49]. Beagan developed a nanosorbent by coating Fe 3 O 4 NPs with MSNs and modifed with aspartic acid via a hydrophobic linker to efectively remove MB dye from contaminated water, and the maximum adsorbed amount of MB was estimated to be 135 mg/g at 200 mg/L MB concentration and 80 minutes' contact time [52]. Magnetic MSNs modifed with poly(2methacryloyloxy) ethyl trimethylammonium chloride brush were found to be highly efcient in removing MO and bromothymol blue (BT) dyes from contaminated water, with a removal efciency of 100% at 100 ppm and unafected adsorption performance by pH.…”
