“…The kinetics of the photocatalytic degradation rate of the probe molecules was evaluated according to the Langmuir–Hinshelwood kinetic model as given below. 8 equivalent Hinshelwood kinetic model: The photocatalytic degradation efficiency of g-C 3 N 4 @TiO 2 @Fe 3 O 4 NPs for the trimethoprim and isoniazid drug active species was analyzed according to the Langmuir–Hinshelwood kinetic model. The results obtained showed that ∼100% of trimethoprim and isoniazid were photocatalytically degraded in ∼120 and 100 min, respectively ( Figure 7 A).…”

“…Analysis techniques for drug active ingredients include high-performance liquid chromatography (HPLC), gas chromatography–mass spectroscopy (GC–MS), liquid chromatography–mass spectroscopy (LC–MS), and high-performance thin-layer chromatography (HPTLC) . However, direct analysis is not always possible due to complications such as the lowest analyte concentration that these devices can measure, higher than the amounts found in the samples studied, and/or the matrix effects of foreign species present in the sample environment. , Therefore, for the accurate and sensitive analysis of drug active ingredients in the instrumental detection system, a sample preparation method is required to separate drug active ingredients from the matrix environment and bring their concentration to a measurable level …”

In this period when environmental pollution has become uncontrollable, the removal of drug active substances reaching the environment and the analysis of drug active substances in different matrix environments are important for both living life and a sustainable environment. Therefore, the production of multifunctional materials that can be used in these two different processes has gained importance in the literature. Based on this thought, in this study, a g-C 3 N 4 @TiO 2 @Fe 3 O 4 multifunctional nanohybrid material was synthesized and used for magnetic solid-phase extraction (MSPE) and photocatalytic degradation of trimethoprim and isoniazid, used together in tuberculosis treatment. All analyses were performed by high-performance liquid chromatography using a diode-array detection (HPLC-DAD) system. The synthesized material was characterized by X-ray diffraction spectroscopy (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, Brunauer–Emmett–Teller (BET) method, ζ-potential analysis, field-emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDX). Important analytical parameters for the MSPE method such as the pH value of the sample solution, the volume of the sample solution, the amount of the sorbent, the type and volume of the elution solvent, and extraction time were optimized. The optimized MSPE method was then applied to different environmental waters and pharmaceutical samples. The recovery percentages for these samples were found to be between 95 and 107%. For trimethoprim and isoniazid, the limit of detections (LODs) were 0.055 and 0.145 and the limit of quantifications (LOQs) were 0.167 and 0.439 ng·mL –1 , respectively. It was observed that ∼100% of trimethoprim and isoniazid active components were photocatalytically removed from the g-C 3 N 4 @TiO 2 @Fe 3 O 4 nanohybrid material in ∼120 min under UV light.

“…Despite all the above, SHSs have not attracted the interest compared with other alternative solvents used in liquidphase microextraction techniques. First of all, in spite of employing CO 2 for the solubilization step, the subsequent pH change is normally performed with strong acids [14][15][16] or strong bases [17,18]. Second, about their safety, some SHSs (especially, those formed from secondary amines) are expected to be safer than traditional solvents in some terms like flammability or smog formation [19].…”

Dispersive liquid-liquid microextraction is one of the most widely used microextraction techniques currently in the Analytical Chemistry field, mainly due to its simplicity and rapidity. The operational mode of this approach has been constantly changing since its introduction, adapting to new trends and applications.Most of these changes are related to the nature of the solvent employed for the microextraction. From the classical halogenated solvents (e.g., chloroform or dichloromethane), different alternatives have been proposed in order to obtain safer and non-pollutants microextraction applications. In this sense, low density solvents, such as alkanols, switchable hydrophobicity solvents and ionic liquids were the first and most popular replacements for halogenated solvents, which provided similar or better results than these classical dispersive liquid-liquid microextraction solvents.However, despite the good performances obtained with low density solvents and

“…A negligible amount of organic solvent is used for the extraction and pre-concentration of the sample before analysis [62][63][64][65][66][67][68][69][70]. Microextraction has different modes such as vortex-assisted liquid-liquid microextraction [71, 72], solid-phase microextraction (SPME) [73][74][75][76][77][78][79][80][81][82][83][84][85][86] and liquid-phase microextraction (LPME) [75,77,79,[87][88][89][90][91][92][93], Dispersive liquid-liquid microextraction (DLLME) [75,94], cloud point extraction, (CPE) [95][96][97][98][99], single-drop microextraction (SDME) [100], ionic liquid-based dispersive liquid-liquid microextraction (IL-DLLME) [101,102] dispersive liquid-liquid microextraction based on solidification of floating organic drop (DLLME-SFO) [103]. However, the recent trends involve the miniaturization of the conventional liquid-liquid extraction principle.…”

Supramolecular solvents (SUPRASs) have rapidly gained more attention as a potential substitute to organic solvents in the sample preparation and pre-concentration process. The essential properties of SUPRAS solvents (e.g., multiple binding sites, different polarity microenvironments, the opportunity to tailor their properties, etc.) these qualities offer numerous opportunities to advance innovative sample preparation and pre-treatment platforms compared to the traditional solvents. Among these qualities, certain importance is placed on theoretical and practical knowledge. That has assisted in making significant developments in SUPRAS that advance our understanding of the processes behind SUPRA'S formation. The SUPRA-solute interactions that drive extractions are explored in this context to develop knowledge-based extraction techniques. This review mainly focused on the significant application of supramolecular-based solvents (SUPRASs) in microextraction techniques.SUPRASs-based liquid-phase microextraction (LPME) is an excellent tool for extracting, simple preparation, and pre-concentration from complex environmental samples. SUPRASs-LPME has a wide range of applications for analysing food, environmental samples, pharmaceuticals, and biological samples.
