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.

“…Their maximum capacities ( q max ) were predicted to be 953.98 and 369.05 mg g −1 , respectively, and the introduced amido (CONH 2 ) and the amino (NH 2 or NH) were beneficial. Tokalioglu et al 15 got the conclusion that the CONH 2 and the sulfonic (SO 3 H) on the polymers were helpful for the efficient preconcentration of Pd 2+ from aqueous solution. Additionally, Zhao et al 16 used pyromellitic acid as the chemical modifier to have the nucleophilic reaction with poly(glycidyl methacrylate), the q max of Pd 2+ arrived at 206.71 mg g −1 , and ion exchange, electrostatic attraction, and chelating coordination were the main adsorption mechanism.…”

Herein, two sulfhydryl‐functionalized polymers, namely, EDT‐HCPS and TMPMP‐HCPS, were synthesized according to the Friedel‐Craft s alkylation and nucleophilic substitution, and they were used to adsorb Pd2+ and Ag+ from aqueous solution. The Friedel‐Crafts alkylation offered the polymers with hyper‐cross‐linking frameworks composed of plentiful rigid methylene. The nucleophilic substitution brought abundant functional SH groups (the sulfur contents were 12.6 and 9.4 wt%, respectively) to the polymers. The adsorption results showed that the capacities of Pd2+ and Ag+ on EDT‐HCPS were larger than TMPMP‐HCPS, and the higher quantities of functional SH groups and the porosity played a beneficial role. The equilibrium data can be characterized by the Langmuir model, and the maximum capacities of Pd2+ and Ag+ on EDT‐HCPS at 308 K were predicted to be 383.92 and 212.93 mg g−1, respectively. The produced polymers represented superior adsorption selectivity, reproducibility, and reusability, demonstrating their excellent performance for the adsorption of Pd2+ and Ag+, and analysis of the adsorption mechanism demonstrated that the SH groups played a major role due to the strong chemical complexation of the functional SH with Pd2+/Ag+.

“…Therefore, it has found an extensive range of applications in metallurgy, petrochemistry, electronics, telephone circuits, dental and medicinal prostheses, jewelry, and coating agents [2][3][4][5]. Catalytic converters of modern vehicles are considered to be the main sources of Pd(II) pollution, because particles deposited on the roadside can be transported to water, leading to the contamination of plants and food [6].…”

In this work, magnetic Fe 3 O 4 nanoparticles (NPs) were synthesized by ultrasonic chemical co-precipitation method. Then hydrophobic ionic liquid (IL), as a green coating agent, was deposited on the surface of synthesized NPs in order to improve their extraction capability toward Pd(II) ions as diethyldithiocarbamate (DDTC) complex. Scanning electron microscopy, thermogravimetric analysis, X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and Fourier transformed infrared (FTIR) techniques were used for characterization of the adsorbent. The adsorption rate was fast and the equilibrium time was achieved within 4 min due to the strong interaction of Pd-DDTC complex with the IL and the absence of internal diffusion resistance. The separation of the adsorbent from aqueous bulk was achieved after about 2 min by a magnet, so no centrifugation or filtration was required. The effective parameters such as pH, concentration of ligand, amount of adsorbent, and the extraction time were inspected by using a central composite design in order to identify the most important parameters and their interactions. Under optimum conditions, the detection limit was 0.82 ng mL −1 and the relative standard deviation (n = 10) was 2.8% for 100 ng mL −1 of Pd(II). The proposed method was applied for the preconcentration of Pd(II) from road dust, liver, and water samples, and it was found that the amounts of palladium ions in dust and liver samples were 104 and 8.7 ng mL −1 , respectively.
