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.

“…The figures of merit of the proposed FI-FDSE-FAAS method and other selected on-line SPE methods coupled to FAAS [8,10,12,14,15,18,24,[30][31][32][33][34][35][36][37][38][39][40][41][42][43], are compiled in Table S1 (Supplementary Materials). The proposed method features good sensitivity and precision with better or similar detection limits than earlier works for Cu(II) [8,15,31,32,34], Ni(II) [8,[38][39][40], Zn(II) [41][42][43], Pb(II) [8,24], and Cd(II) [24] assays, using a shorter preconcentration time.…”

On-Line Fabric Disk Sorptive Extraction via a Flow Preconcentration Platform Coupled with Atomic Absorption Spectrometry for the Determination of Essential and Toxic Elements in Biological Samples

Fabric phase sorptive extraction (FPSE) has gained notable attention and interest both in batch and automatic mode utilizing advanced sol-gel derived microextraction sorbents and the hydrophobic/hydrophilic properties of fabric substrates. Recently, the innovative on-line fabric disk sorptive extraction (FDSE) has opened new opportunities in the field of automatic sample preparation (preconcentration/separation). A novel sol-gel sorbent based on caprolactone-dimethylsiloxane-caprolactone block polymer comprised of a non-polar dimethylsiloxane and hydrophilic caprolactone as a coating on hydrophobic polyester fabric substrate and its evaluation in an automatic FDSE system coupled with flame atomic absorption spectrometry (FAAS), is presented for the first time. The capabilities of the proposed flow injection system were assessed for trace Cu(II), Ni(II), Zn(II), Pb(II), and Cd(II) determination in urine samples. The method was based on the on-line formation of target analytes with ammonium pyrrolidine dithiocarbamate (APDC) and their retention onto the surface of the fabric disk medium. Methyl isobutyl ketone (MIBK) was used to elute metal-APDC complexes directly into the nebulizer-burner system of FAAS. For 90 s of preconcentration time, enhancement factors of 250, 130, 185, and 36 and detection limits (3 s) of 0.15, 0.41, 1.62, and 0.49 µg L −1 were obtained for Cu(II), Ni(II), Pb(II), and Cd(II), respectively. For 30 s of preconcentration time, an enhancement factor of 49 and a detection limit of 0.12 µg L −1 was achieved for Zn(II) determination. The precision, expressed as relative standard deviation (RSD), was lower than 3.5% for all metals. The accuracy of the proposed method was sufficient and evaluated by analyzing certified reference materials and biological samples.

“…Zn (II), which is present in the variety of foods has an important role in the enzymes operations. It is an essential element for the proper functioning of the immune, cellular replication, digestive and nervous systems [1,2]. The low concentrations of this element can be harmful for plants, animals and human body due to its bioaccumulation, nonbiodegradable properties and its toxicity for the brain [3].…”

A new Schiff base, 2-[(4-Chloro-2-oxo-2H-chromen-3-ylmethylene)-amino]-propionic acid was successfully synthesized and characterized by proton nuclear magnetic resonance ( 1 H NMR), carbon-13 nuclear magnetic resonance ( 13 C NMR), Fourier transform infrared (FT-IR), elemental analysis (CHN) and UV-Vis spectroscopy. It was found out that the synthesized Schiff base could be used as a novel and reliable candidate to detect and quantify of Zn (II) ions in water and biological samples. Some effective parameters on quantification of Zn (II), such as pH, Schiff base and salt concentration were inspected by a (2 3 ) full factorial design using Design-Expert, software. Under optimum conditions, the calibration graph was linear in the range 0.04-10.0 μg mL −1 with a limit of detection of 0.01 μg mL −1 . The proposed method was successfully applied to the rapid determination of Zn (II) in water and biological samples. The validation was performed by inductively coupled plasma atomic emission spectrometry (ICP-AES) with satisfactory results.
