Synthesis and application of chelating resins based on polyacrylonitrilediethylenetriamine for metal ions removal
Chelating resins based on polyacrylonitrile and diethylenetriamine (PAN-DTA) wereprepared through the simple reaction of polyacrylonitrile with various volume percents ofdiethylenetriamine (DTA), (25, 50, 75 and 100). The prepared resins were applied to removeheavy metal ions such as Cu(II), Zn(II) and Cd(II) from aqueous solutions. The sorptionbehaviors of the resins for these metal ions were ...
متن کاملSynthesis and metal ion uptake studies of chelating resins derived from formaldehyde-furfuraldehyde condensed phenolic Schiff bases of 4,4'-diaminodiphenylether and o-hydroxyacetophenone.
Two new chelating resins (o-HAP-DDE-HCHO and o-HAP-DDE-FFD), having multiple functional groups are synthesised by condensing the Schiff base of o-hydroxyacetophenone-4,4'-diaminodiphenylether (o-HAP-DDE) with formaldehyde and furfuraldehyde, respectively. The extent of loading of metal ions Cu(II) and Ni(II) was studied in both competitive and non-competitive conditions varying the time of cont...
متن کاملSupported Liquid Membrane in Metal Ion Separation: An Overview
Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
متن کاملPreliminary Adsorption study for Heavy Metal Removal with Ion-Exchange Resins in the Teaching Laboratory
This paper reports on the adsorption of Cr(VI), Cu(II) and Pb(II) from laboratory solution by the use of Chelex 100 (C100) and Amberlite IRA400 ion exchange resins. Metal loading at initial pHs of 3 to 8 at 1-100 mg/L were studied based on Q max and K f values of the Langmuir and Freundlich isotherm models, respectively. Lead was sorbed the most (Q max = 75.19 mg/g, at pH 6), followed by Cu (Q ...
متن کاملRemoval of Heavy Metal from Contaminated Soil with Chelating Agents
Removal of copper and nickel by the addition of the biodegradable chelating agent, chitosan and ethylenediamine tetraacetic acid (EDTA), was investigated, alongside the reaction of a reference compound sodium citrate for comparison. The artificial-contaminated soils were used in this study. The experiments showed that the extraction ability for copper and nickel from the contaminated soil decre...
