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.

“…Poly(N,N 0 -dipropionitrile methacrylamide-co-divinylbenzene-co-2-acrylamido-2-methyl-1-propanesulfonic acid) resin was also synthesised as chelating adsorbent for Cr species in water and food samples by FAAS. 135 The sorption capacity of the resin was found to be 12.1 mg g À1 for Cr III . A preconcentration factor of 150 with a RSD of 2.0% (n ¼ 10) were obtained.…”

In the reported work, a solid phase extraction method for speciation of chromium species in contaminated industrial and river water samples has been studied by using both experimental and computational methods. Multiwalled carbon nanotubes (MWCNTs) functionalized with tris(2‐aminoethyl)amine (TREN) was used as a solid phase extractant for the hyphenated preconcentration of chromium species. The characterization of the immobilized MWCNTs was done by FTIR and SEM analysis. This hyphenated system significantly improves the overall analytical performance by reducing sample consumption and sampling time. The computational results supported the experimental findings. The negative adsorption energy (−2.71 eV) suggested that the interaction process between chromium and modified nanoadsorbent is spontaneous. The system showed a limit of detection of 0.07 μg L−1 at optimized condition with an RSD value of 1.2 %. Adsorption capacity was measured using Lagergren's equation which showed that adsorption kinetics follows pseudo second‐order. The suggested method was applied to contaminated real water samples by performing spike recovery tests. The validation of the reported system was done by analysing NIST Standard Reference Material Trace Elements in Natural Water 1640a.
