Removal of antibiotics from contaminated water is very important because their harmful effects on the environment and living organisms. This study describes preparation a bionanocomposite carboxymethyl tragacanth gum-grafted-polyaniline γFe2O3 using an in situ copolymerization method as effective adsorbent for amoxicillin antibiotic remediation polluted water. The prepared materials were charac...

Background: Polysaccharides are renewable biodegradable natural materials and are accounted for to control the formation of hybrid silica nanocomposites by sol gel process. Methods: The synthesis of templated silica xerogel essentially includes two critical steps of hydrolysis and polycondensation reaction that are started by catalyst and silica precursor solution. Aside from this Saponificatio...

Abstract Plasma polymers from glycidol vapors are of interest for direct covalent grafting molecules bearing amine or thiol groups. The question whether pulsed plasma operation might lead to a higher surface density epoxide groups and grafted is studied using the antifungal drug caspofungin. X‐ray photoelectron spectroscopy Time flight‐secondary ions mass spectrometry analysis followed by caspo...

Graphene oxide (GO) is a promising 2D material with complex chemical structure which characterization remains as challenge. The widely-accepted of GO includes epoxides, hydroxyls and carboxylic acids. Recently, alkene groups have been used for selective functionalization. Despite the different efforts that exist to elucidate exact structure, composition main functionalities fairly limited. By k...

A facile magnetic solid phase extraction (MSPE) of aflatoxins (AFs) from liquid samples was developed using polydopamine-coated magnetic nanoparticles (PD-MNPs) as the adsorbent. PD-MNPs were prepared from amine-terminated MNPs and dopamine via an in situ oxidative self-polymerization approach. Under the selected MSPE conditions, extraction yields ranging from 59.3% for AF G2 to 89.0% for AF B1...

In this article, we describe the application of surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) with the use of amine functionalized graphene-coated cobalt nanoparticles (CoC–NH2 nanoparticles) to analyse aromatic hydrophobic compounds that are known environmental contaminants, including polycyclic aromatic hydrocarbons (PAHs) and pentachlorophenol (PCP). Our results d...

In this study, amine functionalized Kit-6 silica mesoporous magnetite nanocomposite (NH2-MMNC) was synthesized by chemical methods and used as an efficient and recoverable adsorbent for removal of Ponceau 4R, as a toxic dye, from aqueous solutions. The synthesized nanocomposites were characterized by XRD, FT-IR, BET and SEM instruments. The effect of various experimental parameters on the dye r...
