Removal of Lead from Aqueous Solutions by Polyacrylic Acid-Bentonite Composite: Batch and Column Studies
Shortage of water resources and deterioration of water quality have urged the need to develop new technologies for the removal of contaminants from water. Heavy metals produced by municipal and industrial activities are among the most toxic contaminants present in the natural and waste waters. Different methods have been developed for the elimination of heavy metals from water resources and ind...
متن کاملStabilization of magnetorheological suspensions by polyacrylic acid polymers.
This work is devoted to the synthesis and stabilization of magnetorheological suspensions constituted by monodisperse micrometer-sized magnetite spheres in aqueous media. The electrical double-layer characteristics of the solid/liquid interface were studied in the absence and presence of adsorbed layers of high molecular weight polyacrylic acids (PAA; Carbopol). Since the Carbopol-covered parti...
متن کاملInteractions of charged porphyrins with nonionic triblock copolymer hosts in aqueous solutions.
The extent and locus of solubilization of guest and self-assembling surfactant host molecules in aqueous solutions are influenced by a variety of hydrophobic and hydrophilic interactions, as well as by more specific interactions between the various species present. By using a combination of two-dimensional heteronuclear 13C[1H] NMR correlation experiments with pulsed-gradient NMR diffusion and ...
متن کاملIsoprenylation of Polyphenols in Aqueous Acid Solutions
Matract-Polyphenok condens with 2-methylbut-3cne-2-d or y,ydimethylallyl alcohol in 5% aqueous citric acid solution to yield phenolic 2Jdimethylchromans These facik condensation provide chemical support for the biogenetic theory of C-isopentenylation of phenols by 7,7dimcthylallyl pyrophosphate. Iso-psoralidin (20) has been synthesized from 7-hydroxy-2Jdimethylchroman (12) by a novel and conven...
متن کاملSpeciation in aqueous solutions of nitric acid.
In this study, speciation in aqueous solutions of nitric acid at 25 °C was assessed in two independent ways. First, Raman experiments were carried out and interpreted in terms of free nitrate ions, ion pairs and neutral HNO(3) molecules. In parallel, a model was developed to account for the formation of these two kinds of pairs. It was based on an extension of the binding mean spherical approxi...
