Semi-interpenetrating Network-Coated Silica Gel Based on Green Resources for the Efficient Adsorption of Aromatic Pollutants from Waters
نویسندگان
چکیده
In the framework of development green analytical chemistry, a silica gel (SG) coated with semi-penetrating network based on partially biosourced poly(ethersulfone) is studied for greener extraction process aromatic organic pollutants. An optimized composition (80% linear polymer (LP): isosorbide-based and 20% cross-linking agent (XP) type bismaleimide) leads to total adsorption selected pollutants, whatever their hydrophilicity. Adsorption characteristic, kinetics isotherms SG-semi-INP LP80/XP20 p-hydroxybenzoic acid toluic were studied. Langmuir model led better fitting isotherms; easier than that acid. 1/n values benzoic was lower compared biochar cross-linked methacrylate resin, showing higher efficiency.

The substantial aggregation of pristine graphene nanosheets decreases its powerful adsorption capacity and diminishes its practical applications. To overcome this shortcoming, graphene-coated materials (GCMs) were prepared by loading graphene onto silica nanoparticles (SiO2). With the support of SiO2, the stacked interlamination of graphene was held open to expose the powerful adsorption sites ...

Silica gel has been used for synthesis of biscoumarin derivatives starting from 4-hydroxycoumarin and aryl aldehydes. The reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. This method is also simple and inexpensive and leads to high yield of products in short reaction times.
