We successfully synthesized TMU-24 as metal-organic framework (MOF) and employed as an effective sorbent for preconcentration of the letrozole (LTZ) from biological samples. Using high-performance liquid chromatography with UV detector (HPLC-UV) coupling with solid-phase extraction (SPE) a sensitive, fast, and simple method for deteing of LTZ has been developed. The optimal conditions, such as pH, type of eluent solvents, contact time amount of adsorbent, and adsorption capacity were discussed. Under the optimized conditions, relative recoveries (RR) and preconcentration factor (PF) of the LTZ was obtained in the range of 92.4–99.6% and 33 respectively. Under the optimal conditions, LTZ can be determined with a limits of detection (LODs)
To date, a range of liquid-liquid phase separation strategies based on surfactants have often been used in analytical chemistry in which coacervation is influenced by exterior conditions, such as the pH, electrolytes, and temperature. The corresponding surfactant-rich phase, recognized as the supramolecular solvent, is a nano-structured liquid obtained using a two-step sequential molecular and nano self-assembly process. This article includes (i) the synthesis of supramolecular solvents with and without external forces such as vortex shaking and sonication, (ii) the synthesis and utilization of recently designed solvents, and (iii) their versatility in liquid-liquid extractions associated with various analytical instruments.

A method for polypyrrole (PPy) fiber fabrication through a simple and quick one-step electrodeposition process was developed. 3-Hydroxy-4-nitroso-2,7-naphthalenedisulfonic acid was used as an anion dopant for the first time. It was applied for headspace-solid phase microextraction (HS-SPME) of diazinon (DZN) and chlorpyrifos (CPF). A gas chromatography equipped with mass spectrometry was employed for isolation and single ion monitoring of DZN and CPF. Under optimal conditions, linear regressions in the concentration ranges of 0.25–300 ng mL−1 (R2 > 0.99) were achieved. The limits of detection of DZN and CPF were found to be 0.02 and 0.03 ng mL−1, respectively. The developed HS-SPME was employed for analysis of DZN and CPF in five real
Characterization of magnetic nanomaterials (MNMs) is usually accompanied by challenges such as lack of reference materials for calibration of equipment, interpretation of results due to the interdisciplinary nature of this branch, and difficulties associated with sample preparation. There is currently no standard protocol for nanomaterial characterization. Valid and robust measurement methods for MNMs have a major impact on the uptake of these materials in analytical applications. Typically, size and morphology, surface charge and surface chemistry, crystal structure, and its chemical composition and magnetic behavior are some of the properties that are investigated after MNMs synthesis for analytical applications. In this chapter, common t
In the present study copper based metal‐organic framework (HKUST‐1) was used first time for preconcentration trace amounts of addictive drugs in biological samples. HKUST‐1 was synthesized and coated onto the surface of stainless steel wire. The prepared coating was used in headspace solid phase microextraction method coupled with gas chromatography‐mass spectrometry for preconcentration and determination of some addictive drugs in biological fluids. Prepared coating shows good extraction efficiency due to large surface area, and π–π stacking interaction with selected analytes. Under optimum conditions, the method was validated with a reasonable determination coefficient (R2 > 0.9961) and suitable linear dynamic range (0.5‐10
Porous frameworks are a term of attracting solid materials assembled by interconnection of molecules and ions. These trendy materials due to high chemical and thermal stability, well‐defined pore size and structure, and high effective surface area gained attention to employ as extraction phase in sample pretreatment methods before analytical analysis. Solid‐phase microextraction is an important subclass of sample preparation technique that up to now different configurations of this method have been introduced to get adaptable with different environments and analytical instruments. In this review, theoretical aspect and different modes of solid‐phase microextraction method are investigated. Different classes of porous frameworks and t
To date, the greatest applications of magnetic materials (MNMs)—and perhaps the greatest impact—have been in the field of environmental applications, such as aqueous environment treatment by improving the quality of drinking water resources or by removing industrial pollutants from environmental water samples. Nowadays, MNMs are considered to be an advanced sorbent in the treatment of environmental samples for the purposes of preconcentration and removal of environmental pollutants at trace levels and high levels, respectively. The main advantage of MNMs as sorbents is their magnetic behavior, which allows them to separate pollutants from large volume environmental samples simply and quickly with the aid of a magnet without the need for
Nowadays, magnetic nanomaterials (MNMs) are investigated as emerging sorbents in sample preparation techniques of food samples for the extraction and enrichment of food components and pollutants at trace levels. The main advantage of MNMs as a sorbent is their magnetic behavior by which the magnet can separate the target compounds from the food matrix without the need for tedious filtration and centrifugation steps. Also, nanosized sorbents possess high surface areas and short diffusion routes that lead to higher extraction capacities and extraction efficiencies. In this chapter, the applications of nanomaterials as sorbents in food analysis will be reviewed. Initially, the properties of some of the advanced and important nanomaterials used
In this chapter, preconcentration and cleanup characteristics of surface-active agents in solvent extraction are discussed. Their amphiphilic nature creates an affinity for interaction with target analytes at interfaces of water/organic solvents or water-/surfactant-rich phase. The type of surfactant and the interaction of surfactant with organic molecules/metal cations and also the matrix predict the level of extraction performance. Formulation and understanding the behavior of surfactants in liquid solution are critical to optimal application of surfactants in LLE techniques. Surfactants have been studied at three major categories of solvent extraction including extractant, disperser, and ion-pairing agent. (I) Surfactants at above CMC co
In the present work, an ion-pair based dispersive liquid-liquid microextraction was performed on a centrifugal chip for the first time. The entire DLLME procedure, including flow direction, desperation, and sedimentation of the extracting phase, can be fulfilled automatically on a solitary chip. The chip was made of Poly(methyl methacrylate) (PMMA) and was of two units for two parallel extractions, each consisting of three chambers (for the sample solution, extracting solvents, and sedimentation). As the chip rotated, fluids flowed within the chip, and the dispersion, mixing, extraction, and sedimentation of the final phase were performed on the chip by simply adjusting the spin speed. Determination of two histamine H2 receptor antagonist d
In this work, an imine-based covalent triazine framework (IB-CTF) was synthesized and thoroughly characterized by TGA, FT-IR, XRD, and FE-SEM. Then, its application was investigated in head-space solid-phase microextraction (HS-SPME) of Chlorophenols (CPs) from aqueous solutions. The selected CPs (2,4-dichlorophenol (2,4-DCP), 2,3-dichlorophenol (2,3-DCP), and 3,5-dichlorophenol (3,5-DCP)) were successfully extracted in only 30?min. The presence of hydrogen bonding and π-π interactions between the adsorbent and the above-mentioned CPs led to better extraction. The obtained results confirm the application of CTFs as adsorbents in HS-SPME in wastewater treatment.
