Adsorption behaviour of copper(II) ion from aqueous solution on 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(2002)
The adsorption behaviour of 4 vinyl pyridin grafted poly (ethylene terephthalate) fibers was studied towards the copper (II) ions in aqueous solutions by a batch equilibriation technique. The influence of treatment time, ...
Reverse Engineering To Characterize Redox Properties: Revealing Melanin's Redox Activity through Mediated Electrochemical Probing
(Amer Chemical Soc, 2018)
Melanins are ubiquitous in nature, yet their functions remain poorly understood, because their structures and properties elude characterization by conventional methods. Since many of the proposed functions of melanins ...
Voltammetric determination of Hg(II) at poly(2-aminothiazole) modified platinum electrode.
(Parlar Scientific Publications (P S P), 2011)
Conducting poly(2-aminothiazole) (PAT) film was electrodeposited on platinum disc electrode surface by cyclic voltammetry of 2-aminothiazole (AT) for stripping voltammetric determination of Hg(II). Hg(II) was pre-concentrated ...
The effect of preparation procedure for precursor on the morphology, surface area and porosity of alumina powders
(Asian Journal Of Chemistry, 2008)
In order to investigate the effect of preparation procedure for precursors on some physico-chemical properties of powders, three alumina precursors were prepared by different ways. The first precursor (P1) was precipitated ...
Selectivity and kinetics of ligand exchange of anions in a chelate ion exchanger
(Gauthier-Villars, 1997)
Ligand selectivity plots and interdiffusion coefficients are presented for the chloride form of a ligand exchanger chemically derived from sporopollenin. Exchanges of iodide and bromide for chloride as the ligand were ...
Diffusion and selective transport of alkali cations in a polysulfone ion exchange membrane
(Gauthier-Villars, 1995)
he diffusion of alkali metals through a charged polysulfonated ICE-450 ion exchange membrane has been measured as a function of pH and conservation of the external solution at 25 degrees C. The permeability and diffusion ...
Controlled release of insecticide carbaryl from crosslinked carboxymethylcellulose beads
(Parlar Scientific Publications (P S P), 2004)
Copper-carboxymethylcellulose (CuCMC) beads containing carbaryl were prepared by the ionotropic crosslinking of sodium carboxymethylcellulose (NaCMC) with copper ions. The beads were characterized by carbaryl encapsulation ...
Permeation and separation characteristics of acetic acid/water mixtures through poly(vinyl alcohol-g-itaconic acid) membranes by pervaporation, evapomeation, and temperature-difference evapomeation
(Wiley, 2004)
In this study, itaconic acid (IA) was grafted onto poly(vinyl alcohol) (PVA) with cerium(IV) ammonium nitrate as an initiator at 45degreesC. The grafted PVA was characterized with Fourier transform infrared spectroscopy, ...
