“…Figure 3 shows the experimental data obtained for the selection of the elution solvent for the SPE pre-concentration of 218 multiclass pesticides in water [45]. It can be observed that the most polar pesticides (pKow <4) were completely eluted with acetonitrile, whereas for the less polar pesticides (pKow >4) hexane was the best elution solvent.…”

“…Usually, the development of a SPE procedure for the pre-concentration of analytes in water samples requires the study of the effect of several parameters on the retention/elution of these analytes on the SPE sorbent. Optimization of these parameters can be performed using step-by-step and/or multifactorial experimental design methodologies, being the last approach particularly useful for the pre-concentration of multiclass analytes [45][46][47][48]. In general, step-by-step optimization approach is employed to determine the optimal conditions for independent parameters (e.g.…”

Since the first applications of solids with adsorbent properties in water treatment, Solid-Phase Extraction (SPE) has been the most suitable sample preparation technique for the determination of organic pollutants in water. In the last decades, numerous articles have appeared in the literature describing a wide variety of SPE sorbents. Attention in this field has focused on the search for new SPE materials capable of extracting a wide variety of pollutants from water. However, each sorbent has advantages for certain compounds, but not when it is used with others. Thus, conventional sorbents showed poor performance for most high polarity analytes. Recently, mesoporous materials are attracting increasing interest in sample preparation due to their desirable characteristics. They present unique advantages as highly ordered and size-controlled mesoporous structures, high surface areas and large pore volumes, good performance in thermal and chemical stability, compositional controllability and flexibility for functionalization.

“…Transition metals in bimetal−organic frameworks, in particular, provide free sites that can operate as Lewis basic sites to recognize/adsorb targets, emphasizing their intrinsic features and adding additional qualities to the structure and functionalities of MOFs to widen their potential uses. 37 (2) The structure−performance relationship is another important feature of MOF functions that is sometimes overlooked and undervalued. Because of the distinctive nanoarchitecture, intended composition, and presence of porous structures, nanostructure engineering has proved to be a viable method for improving MOF properties.…”

Quantifying creatinine (Cn) in biological fluids is crucial for clinically assessing renal insufficiency, thyroid irregularities, and muscle damage. Therefore, it is crucial for human health to have a simple, quick, and accurate Cn analysis technique. In this study, we have successfully synthesized a 3D ratiometric dual-metal−organic framework, namely, the amino-MIL-53@Mo/ ZIF-8 and rhodamie B heterostructure, using an internal strategy for sustained growth. The dual-MOF functions as an adsorbent and preconcentrates Cn. The pH, reaction time, and volume ratio of amino-MIL-53@Mo/ZIF-8/rhodamie B were optimized using the one-variable-at-a-time technique in this study. The quantitative study of the Cn concentration for this RF biosensor was obtained under ideal conditions (R 2 = 0.9962, n = 3), encompassing the linear range of 0.35−11.1 μM. The detection and quantitation limits were 0.18 and 0.54 nM, respectively. Both intra-and interday reproducibility showed high repeatability of the RF biosensor, UV−vis, and ZETA potential studies, and the Stern−Volmer relationship was used to clarify the fluorescence quenching process. These superior sensing capabilities and the benefits of simple manufacturing, acceptable stability, and practicality make the RF biosensor intriguing for ultrasensitive Cn detection in practical applications.
