“…The mortar was used to make it fine powder. 36 To synthesize MgAl2O4@MoSe2 nanocomposite, a mixture of 1.0 g of sodium molybdate dihydrate and 0.75 g of MgAl2O4 nanoparticles was combined with a solution containing 20 ml of deionized water and 30 ml of ethanol, resulting in the creation of solution A. Similarly, 0.66 g of selenium powder was dissolved in 15 ml of hydrazine hydrate, leading to the formation of suspension B, which promptly changed color from colorless to very dark violet.…”

“…When MoSe2 is used as a sorbent alone, its efficiency may be limited by its surface area or lack of synergistic interactions with specific analytes. 36,37 The combination of spinel oxides like MgAl2O4 with molybdenum selenide (MoSe2) nanoparticles holds significant importance and offers a range of promising applications across different fields of science and technology. These nanocomposites offer enhanced properties and tunability, enabling customization for specific applications.…”

MgAl2O4@MoSe2 nanocomposite was used to separate-preconcentrate bismuth ions for micro solid phase extraction (µ-SPE). FT-IR, SEM, XRD, SEM-Mapping and SEM-EDX were used to find out about the functional groups, surface morphology, surface area, elemental composition, and crystalline structure of MgAl2O4@MoSe2. Analytical parameters, such as pH, adsorbent dose, sample volume, eluent concentration and volume, vortex time, and matrix effect, were optimized to get the best recovery values. Under optimized experimental conditions and by using FAAS measurements, analytical parameters were calculated, such as the limit of detection, the limit of quantification, the preconcentration factor, the enhancement factor (EF), the relative standard deviation, the sample volume, and the eluent volume as 0.012 μg L -1 , 0.04 μg L -1 , 10, 8.69, 5.5, 30 mL, and 3.0 mL, respectively. The validation of the presented procedure was checked by the analysis of certified reference materials and the addition-recovery test to real samples. The presented method was applied for the determination of bismuth contents of natural water, food, and cosmetic products. Two certified reference materials (CRMs) (NCS ZC 73028 Rice and NCS ZC 73036 Green tea) were used for the validation of the presented method.

“…Furthermore, its small size and integration with analytical equipment make it versatile and suitable for sample preparation in both laboratory and field settings. [31][32][33][34] One material that is appropriate for use in µ-SPE is layered double hydroxide (LDH) nanoparticles. They have many advantages, such as a large and adjustable surface area, excellent selectivity, and increased sensitivity.…”

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.

“…Therefore, the sensitivity and effectiveness of the approach will be significantly influenced by the coating's characteristics [5]. To develop SPME fibers, various compounds, including covalent organic framework [6, 7], ringent multishelled hollow MIL‐88B (RMH‐MIL‐88B) [8], magnetic Luffa@MOF‐199 [9], carbon nano onion/metal‐organic framework [10], zeolitic imidazole framework‐67 (ZIF‐67) [11], MIL‐88B@MIL‐88A@chitosan [12], and ZIF‐8 @ ZIF67/Fe 3 O 4 [13], have been utilized. It is clear that among the various compounds reported as coatings for SPME, MOFs have attracted the attention of many researchers due to their intriguing characteristics [14–16].…”

Herein, the zeolitic imidazolate framework‐8 template was accommodated onto the surface of a pencil graphite substrate through the electrodeposition system. Then, Zn in the zeolitic imidazolate framework‐8 was replaced with Cu atoms via the galvanic replacement procedure. The modified template was used for the synthesis of another metal‐organic framework (copper‐benzene di carboxylic acid) by a solvothermal method. The prepared fiber was characterized by field emission‐scanning electron microscopy, Fourier transform infrared spectroscopy, and X‐ray diffraction technique. Then, it was employed for direct immersion solid‐phase microextraction of methyl, ethyl, and butyl parabens. Various factors, such as the pH of the sample solution, stirring rate, desorption volume, the concentration of salt, extraction time, and desorption time, were selected and optimized. Under the optimized condition (extraction time = 30 min, desorption time = 2 min, desorption volume = 200 μL, salt concentration = 0% w/v, sample solution pH = 3.0, and stirring rate = 700 rpm), the linearity of the method was in the range of 1–200 μg/L (r2 > 0.9926). The limits of detection and quantification fall between 0.28–0.65 μg/L and 0.91–1.98 μg/L, respectively. The analysis of selected parabens in toothpaste and hand and face lotion, were also done using the suggested methodology.
