“…As seen in these figures, the main peaks of LDH have been preserved in nanocomposite, which confirms that the nanocomposite has kept its primary structure after the adsorption of TCs. A little shift in 2θs after adsorption of TCs is observed, which is in accordance with previous studies and confirms the successful loading of thiosulfate anions within the layers of LDH 34. FTIR spectroscopy is a powerful technique for analyzing the structures of LDHs, representing surface hydroxyl groups, vibrations in the octahedral lattice, and the interlayer anions.…”

A new analytical method combining magnetic micro‐solid phase extraction (μ‐SPE) in tandem with high‐performance liquid chromatography‐ultraviolet (HPLC‐UV) analysis was developed and used for the simultaneous extraction/preconcentration of tetracycline (TC) and oxytetracycline (OTC) residues in drug manufacturing effluents. The μ‐SPE conducted by the introduction of iron oxide reduced‐graphene oxide (MrGO) doped tin‐lanthanium intercalated with thiosulfate ions to produce magnetic LDH (MrGO/Sn‐La‐S). The adsorbent was synthesized and characterized using x‐ray diffraction, Fourier transform infrared, scanning electron microscopy, energy‐dispersive x‐ray, elemental mapping, transmission electron microscopy, x‐ray photoelectron spectroscopy, and value stream mapping techniques. The effective parameters, including the extraction and desorption steps, were investigated and optimized. Under optimized conditions, the limits of detection (LOD) for TC and OTC were obtained as 5.42 and 3.31 μg.L−1, respectively, while the linearity was in the range of 10.0–500.0 μg.L−1 for both antibiotics with satisfactory determination coefficients (R2) of 0.9811 and 0.9846 for TC and OTC, respectively. The recovery percentages for the analytes in real samples were achieved in the ranges of 89.2%–101.6% and 91.0%–101.3% for TC and OTC antibiotics, respectively. All these features proved the potential of the developed method and adsorbent for real world applications.

Over the past decade, heterocyclic compounds and their derivatives have emerged as promising substances with potential pharmacological applications due to their interesting biological properties. The significance of heterocyclic compounds in drug discovery and development is evident from the fact that a majority of drugs in the pharmaceutical market incorporate heterocyclic compounds as active substances or ingredients. Various synthetic methods and advancements have been devised to prepare these heterocyclic compounds using diverse catalysts under mild conditions. Layered double hydroxides (LDHs)-based materials have gained considerable attention across different fields, and their usability can be significantly enhanced via the selection of metal cations, their molar ratios, surface complexation, and intercalation modifications. The synthesis and application of LDH-based materials as catalysts have garnered increasing interest due to their exceptional properties. Moreover, LDH-based materials have found extensive use as heterogeneous catalysts in the synthesis of numerous heterocyclic compounds. This review presents the latest developments in the catalytic application of LDH-based materials as solid heterogeneous catalysts in the synthesis of heterocyclic compounds, covering literature published from 2018 to 2023.
