Metal chelate resin

Immunoglobulins G are a peculiar group of metal-interacting proteins as a result of the presence in their structure of a highly conserved histidyl cluster at the junctures of CH2 and CH3 domains of Fc fragment,186 and therefore they are easily adsorbed on metal chelating resins.187... 

In the synthesis of a methacrylate-based metal chelating resin, CP/MAS spectroscopy has been used to confirmed that the target resin had been made [31]. Here the imidazole ligand bis(imidazo-2-yl)methylaminome-thane (bimam) was attached to a glycidyl methacrylate-co-trimethylolpropane trimethylacrylate (pGMT) resin. The peaks in the C NMR spectrum were... 

Another metal chelating resin was looked at using CP/MAS [46] (Fig. 15.2.40). This resin was based on an salicylaldehyde acrylate monomer... 

Cross-Linked Polymers. Apart from the soluble polymers, insoluble resins with unusual functional groups are of interest in areas such as metal-chelating resins. The most promising monomers of Table I were studied as potential resins. To obtain cross-linked polymers without adding new interfering groups, 1,6-diallylaminohexane (XVI) was used in 5-10 mol % quantities as the cross-linking monomer.

The ligand utilization of the metal chelate resin can be characterized by the ratio of ligand density to lysozyme binding capacity. This is shown in Fig. 10.

Pentanedione is widely used in extraction processes for the separation and purification of metals because of its abiUty to form covalent metal chelates. It is also used as an intermediate in the production of heterocycHc substances and dyes, as a fuel additive (324), and in metal plating and resin modification.

The cost of resins is a major consideration. Heavy-metal-selective chelating resins are the most expensive. Table 4 provides some cost ranges for commercially available resins. 

Theory. Conventional anion and cation exchange resins appear to be of limited use for concentrating trace metals from saline solutions such as sea water. The introduction of chelating resins, particularly those based on iminodiacetic acid, makes it possible to concentrate trace metals from brine solutions and separate them from the major components of the solution. Thus the elements cadmium, copper, cobalt, nickel and zinc are selectively retained by the resin Chelex-100 and can be recovered subsequently for determination by atomic absorption spectrophotometry.45 To enhance the sensitivity of the AAS procedure the eluate is evaporated to dryness and the residue dissolved in 90 per cent aqueous acetone. The use of the chelating resin offers the advantage over concentration by solvent extraction that, in principle, there is no limit to the volume of sample which can be used.
