Molecularly imprinted phenyl-functionalized silica aerogels: Selective adsorbents for methylxanthines and PAHs

An Overview and Evaluation of Highly Porous Adsorbent Materials for Polycyclic Aromatic Hydrocarbons and Phenols Removal from Wastewater

“…The adsorptions of PAHs onto the functionalized silica aerogels has been recently reported by Saad et al, (2020). The adsorbent material has proven to be effective in the removal of NAP, ANT, and PYR, with the fluorescence measurements showing effective adsorption and selectivity of the material in the highest order of NAP, ANT, and PYR, respectively [200]. Wei et al (2015) reported on the selective recognition of PAHs by MIPs.…”

“…They are well known for their high porosity resulting from the removal of the template molecules, forming large cavities allows for the easy access of the molecules to the recognition sites [27,199]. The MIPs of inorganic molecularly imprinted materials are more flexible in comparison to those obtained from the organic monomers due to the more availability of the inorganic monomers to be selected from, hence the rigidity of the solid network as well as the adaptable porosity [200].…”

“…They also offer high selectivity to the pollutants, mainly via hydrogen bonding, ion-pair interactions, hydrophobic interactions, and Van der Waals forces [28]. The adsorptions of PAHs onto the functionalized silica aerogels has been recently reported by Saad et al, (2020).

Solid phase extraction based on trimethylsilyloxy silica aerogel

“…12 Aerogels based on carbon and silica have been used to extract pharmaceuticals, metal ions and pesticides. [15][16][17] Due to their high porosity, surface area, mechanical strength, temperature resistance and number of active adsorption sites, silica aerogels offer a promising material for SPE. 12,13 Amine-functionalized silica aerogel was used for separation and pre-concentration of Pb(II) ions in water.…”

Novel Nanocellulose/Polymer Composite Aerogel as Solid‐State Fluorescence Probe by Pickering Emulsion Route

“…[ 1 ] Aerogels are prepared by removing the liquid dispersion medium from the gel without collapsing the network structure. [ 2 ] Various types of aerogels can be fabricated from carbon nanofiber, [ 3,4 ] carbon nanotube, [ 5 ] graphene, [ 6 ] silica, [ 7,8 ] and cellulose. [ 9 ] Among these newly developed aerogels, those based on cellulose have environmentally friendly, renewable, and economic advantages due to cellulose as one of the world's most abundant and rapidly degradable biopolymers, [ 10 ] which have received a lot of attention from many researchers.…”
