“…Overall, these techniques are considered indispensable for obtaining the highquality data required to assess the presence and impact of trace metals in soil, thereby informing environmental management, risk assessment, and regulatory compliance. [28][29][30] The micro-solid phase extraction (µ-SPE) approach provides various benefits over standard sample preparation methods. One prominent benefit is a considerable decrease in chemical and solvent use, which leads to better environmental and financial efficiency in studies.…”

Layered double hydroxides (LDHs) are a class of materials that may be readily synthesized in a laboratory environment. This work successfully conducted the synthesis of a new nanomaterial (ZnMnAl LDH). The characterization of this material was accomplished utilizing many analytical techniques, including FTIR, XRD, SEM-mapping, and FE-SEM. ZnMnAl LDH was employed to separate and enrich Cu(II) and Ni(II) from soil and water samples. The Cu and Ni ions were eluted from ZnMnAl LDH nanoparticles by using 2 mL of 0.1 mol L −1 of HNO3. The metal ions were quantified using flame atomic absorption spectrometry (FAAS). An investigation was conducted to examine the impact of many analytical factors on the efficiency of metal ions' extraction. These parameters include pH, sorbent amount, eluent volume, eluent concentration, sample volume, and possible interfering ions. The detection limits for Cu(II) and Ni(II) were found to be 0.74 and 0.52 μg kg −1 , respectively. In addition, the relative standard deviation (RSD%) for Cu(II) is 3.8 and for Ni(II) is 1.9. The linear range for both analytes is 50-1000 μg L −1 , and the preconcentration factor is 15 for both. The method's validation was verified by the analysis of certified reference materials, namely BCR-505 estuarine water and GBW07429 (GSS-15) soil. For soil samples, Ni(II) and Cu(II) concentrations vary from 9.8 to 62.8 mg kg -1 and 9.9 to 73.5 mg kg -1 , respectively. The technique described was used to quantify trace concentrations of copper (Cu) and nickel (Ni) in samples of both natural water and soil.

“…There are several methods for extracting and preconcentrating heavy metals from natural matrices, such as ion exchange [16], co-precipitation [17], coagulation [18], chemical precipitation, cloud point extraction [19], and liquid-liquid extraction (LLE) [19], reverse osmosis [20], membrane filtration [21], coagulation [18], co-precipitation [17], electrochemical precipitation [22] and SPE have been developed. Among the mentioned methods, SPE is the most widely used method for the pre-concentration of heavy metal ions from environmental samples due to its ease, speed, low cost, and minimal reagent consumption [23].…”

In this study, Pb(II) and Cd(II) ions were determined by Fe3O4@G2/Npht magnetic dendrimers using the solid-phase extraction (SPE) method by flame atomic absorption spectrophotometer (FAAS). The morphological and chemical properties of magnetic dendrimers were investigated using Fourier Transform Infrared (FTIR) spectroscopy and transmission electron microscopy (TEM) techniques. The magnetic characteristics of the ferromagnetic features of the magnetic nanocomposites were validated by vibrating sample magnetometry (VSM). The heavy metal ion recovery was assessed via flame atomic adsorption spectroscopy (FAAS). To ascertain the ideal adsorption system conditions, the effects of various parameters, including pH, adsorbent dose, adsorbent time, eluent type and amount, etc., were examined. Optimum conditions for heavy metal recovery using Fe3O4@G2/Npht magnetic dendrimer were determined as pH 6.5, 1M HNO3 and 100 mg for Pb(II) and pH 7.5, 1 M HNO3 and 100 mg for Cd(II). The novel material of Fe3O4@G2/Npht magnetic dendrimer for separation and pre-concentration of Pb(II) and Cd(II) was used to natural water.
