“…Active carbon, metal oxides, peanut skins, wool, and cotton [5][6][7][8] have been used as adsorbents for adsorption of heavy metal ions. Reactive polymers are another group of materials that are used in the selective extraction of metals from aqueous solutions [9][10][11]. In particular, the fibrous reactive materials have a very high adsorption capacity due to their very large surface area.…”

“…The electron spin resonance (ESR) studies carried out on PET revealed that there formed two types of radicals, whose structures are given below: 30,31 These radical sites can be created either by the direct interaction of the initiator with the fibers or by the transfer reaction between the active homopoly (CN) chains and PET fiber. [32][33][34] Type II PET radicals are known to be predominant.…”

In this study, a fibrous adsorbent containing amidoxime groups was prepared by graft copolymerization of acrylonitrile (AN) onto poly(ethylene terephthalate) (PET) fibers using benzoyl peroxide (Bz 2 O 2 ) as initiator in aqueous solution, and subsequent chemical modification of cyano groups by reaction with hydroxylamine hydrochloride in methanol. The grafted and modified fibers were characterized by FTIR, TGA, SEM, and XRD analysis. The crystallinity increased, but thermal stability decreased with grafting and amidoximation. The removal of Cu(II), Ni(II), Co(II), Pb(II), and Cd(II) ions from aqueous solution onto chelating fibers were studied using batch adsorption method. These properties were investigated under competitive conditions. The effects of the pH, contact time, and initial ion concentration on the removal percentage of ions were studied. The results show that the adsorption rate of metal ions followed the given order Co(II) > Pb(II) > Cd(II) > Ni(II) > Cu(II). The percentage removal of ions increased with initial ion concentration, shaking time, and pH of the medium. Total metal ion removal capacity was 49.75 mg/g fiber on amidoximated fiber. It was observed that amidoximated fibers can be regenerated by acid without losing their activity, and it is more selective for Pb(II) ions in the mixed solution of Pb-Cu-Ni-Co-Cd at pH 4.

“…Some adsorbents are also difficult to revive and cannot be reused. Polymer resins with different functional groups and large surface area are broadly used for the separation of metal ions and enrichment of trace elements [3,4]. Recently, the importance of removing heavy metal ions from aqueous media has been increasing for the purpose of control environmental pollution.…”

Trace Metals in the Environment - New Approaches and Recent Advances

The waste of trace metals are led the pollutions of water, soil and air. That's why the accurate and sensitive identification of amount of trace metals in food samples and environment are gained importance in analytical chemistry because of their toxicity to human health. Besides, the direct determination of trace metals, presented at very low concentration especially in real samples, is difficult. In this content, before determination of trace metals by instrumental methods can be achieved successfully using separation/preconcentration procedures. The different synthesized chelating polymer resin adsorbents are successfully used for the SPE of trace metals. The trace metals, such as Cu, Cr, Co, Mn, Zn and Fe, are necessary for human health, when it has been taken at certain limits. But, the trace metals, such as Hg, Cd, Pb, Ni and As are toxic metals for the human body. About this, there are studies on the determination of trace elements and mineral in food samples and environment. In this study, new methods in the synthesis of (meth)acrylamides and use as a sorbent in the trace metals extraction was identified.
