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 کامل[Ion exchange resins].
Ion exchange resins have been used to help formulate pharmaceuticals since the late 1950's. During that time they have proved to be safe and effective excipients and are now used in many commercial formulations throughout the world. In this article we will look at some of the common problems faced by formulators and how using ion exchange resins may be able to solve them. Ion exchange resins ar...
متن کاملSeparation and concentration of molybdenum(VI) and tungsten(VI) with chelating ion-exchange resins containing sulphur ligands.
Three chelating ion-exchange resins based on macroreticular polyacrylonitrile-divinylbenzene copolymers with thioglycollic acid and cysteine as functional groups have been tested for separation of molybdenum(VI) and tungsten(VI). On a short column of the thioglycollic acid resin, molybdenum(VI) and tungsten(VI) can be selectively sorbed from pH-4.3 acetate buffer and eluted with 2M hydrochloric...
متن کاملMetal Sorption of Macroreticular Poly(4-vinylpyridine) Resins Cross-Linked with Oligo(ethylene glycol dimethacrylates)
Poly(4-vinylpyridine), 4VP, resins cross-linked with oligo(ethylene glycol dimethacrylates) were used for chelating resins. Sorption for some metal ions by complexation in acetate buffer (pH 3-6) was investigated mainly by using the 4VP resins cross-linked with hydrophilic tetraethylene glycol dimethacrylate (4VP-4EG) and that cross-linked with hydrophobic divinylbenzene (4VP-DVB). The differen...
متن کاملChipal Chelating Resins in Chromatogpaphy of Optical Isomers
The ways of binding optically active ligands, mainly of the amino acid type, to cross—linked polymers of styrene, acrylamide or glycidylmethacrylate are reviewed. When coordina— ted to transition metal ions, these polymers display a high discriminating ability in sorption of optical isomers of corn— pounds capable of forming mixed—ligand complexes. The kinetic performance of the ligand—exchangi...
