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, ...
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 ...
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, ...
