Study of Metal Ion Removal from Aqueous Systems Using Magnetic Nanostructures Based on Functionalized Poly(Benzofuran-co-Arylacetic Acid)

Metal pollution has become a worldwide problem, mainly because of the toxicity, effects on living organisms, and the impact on the food chain and the quality of drinking water. Researchers have been focusing on developing new materials through green chemistry methods in order to remove these pollutants from the environment. In the recent decades, due to their unique properties, magnetic nanostructures containing functionalized polymers as shells have been demonstrated to be useful in water and wastewater treatment for this application. In this study, we report the synthesis and characterization of hybrid magnetic core-shell nanostructures including magnetite as the inorganic core and poly(benzofuran-co-arylacetic acid) functionalized with N alpha, N alpha’-bis(carboxymethyl)-L-lysine as the organic shell. These nanomaterials were used in the adsorption of different metal ions from aqueous solutions and contaminated water samples collected from Rosia River (Rosia Montana, Romania), representing attractive alternatives for water and/or wastewater treatment. The properties of the magnetic hybrid nanostructures were investigated by Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), magnetization measurements. The heavy metal concentrations in aqueous solutions were determined by flame atomic absorption spectrometry (FAAS).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 66357-35-5 is helpful to your research. Product Details of 66357-35-5.

Condensation of ninhydrin with phenols: Regioselective formation of diverse organic scaffolds and crystal structure studies

In the present work, a range of phenolic compounds have been reacted with ninhydrin in acid medium to afford different indanone-based molecules via regioselective C-C bond formation. Ninhydrin reacts with 2,7-Dihydroxynaphthalene and 4-cyanophenol in AcOH producing ortho selective adduct 3a and 3b respectively; however, unlike 3a remaining as cyclic hemiketal structure, 3b exists as ring-opened diketo form. On the other hand, ortho-substituted phenols like o-cresol, guaiacol, o-chloro/iodophenol condense with ninhydrin to accomplish para selective diarylated adducts 5a-d, whereas 3-methoxy phenol provides corresponding monoarylated adduct 5e as the major product. Different hydroxy benzoic acids deliver versatile scaffolds like diarylated indanone, indenofuran, benzofuran or spirolactone 7a-e depending upon the substitution pattern and acidity of the reaction medium. All the compounds are characterized by H-1 and C-13 NMR spectra. In the solid state, scissors-shaped molecule 5a has been found to form inclusion complex with disordered o-cresol molecule and function as building unit of supramolecular network. In the crystal structure of spirolactone 7d, anti-parallel motif of dipolar center dot center dot center dot dipolar (C = O(delta-) center dot center dot center dot C(delta+) = O) interaction results ladder-like arrangement.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 66357-35-5, in my other articles.
