Headspace solid-phase microextraction: Fundamentals and recent advances

Advances in Sample Preparation, Journal Year: 2022, Volume and Issue: 3, P. 100035 - 100035

Published: July 19, 2022

Solid-phase microextraction (SPME) has become a powerful sample preparation technique which allows to efficiently isolate and enrich analytes from complex matrixes. One of the most widespread SPME modes, consists extraction directly headspace (HS) is equilibrated with sample. In this sense, HS-SPME provides one best platforms for preparation, especially analysis volatile semi-volatile organic compounds. Furthermore, demonstrated be versatile, sensitive, robust, environmentally friendly when applied samples coming diverse variety fields such as bioanalysis, environmental sciences, food cultural heritage. Moreover, during last years, implementation dramatically grown along need monitor systems over time using in situ vivo approaches, taking advantage its noninvasive nature. review article, authors present fundamentals aiming critically understand advantages limitations, highlighting recent advances published ten years. To aim, special sections dealing extractive phase development, technological relevant applications different have been carefully designed. Finally, some thoughts perspectives about future are also discussed.

Applications of different adsorbent materials for the removal of organic and inorganic contaminants from water and wastewater – A review

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100253 - 100253

Published: Jan. 1, 2024

Increasing wastewater production is posing a threat to the safety and cleanliness of water. Adsorbents have been used in various industries remove contaminants from wastewater. In this review, naturally occurring laboratory–synthesized adsorbents, their past recent advancements, future treatment strategies are comprehensively described. Nanomaterials (NMs) extensively as adsorbents due high surface area, porosity, low density, chemical stability. For effective implementation, adsorption capacity NMs optimized. Compared larger counterparts, nanomaterials found higher rate constants, making them more adsorbents. The adverse effects associated with synthesis application these discussed. This review also addresses some significant issues concerning which could impact research practical applications nano for water safety.

Extraction of Metal Ions with Metal–Organic Frameworks

Molecules, Journal Year: 2019, Volume and Issue: 24(24), P. 4605 - 4605

Published: Dec. 16, 2019

Metal-organic frameworks (MOFs) are crystalline porous materials composed of metal ions or clusters coordinated with organic linkers. Due to their extraordinary properties such as high porosity homogeneous and tunable in size pores/cages, well thermal chemical stability, MOFs have gained attention diverse analytical applications. been coupled a wide variety extraction techniques including solid-phase (SPE), dispersive (d-SPE), magnetic (MSPE) for the preconcentration from complex matrices. The low concentration levels real samples food samples, environmental biological increased number potentially interfering ions, make determination trace still challenging. A MOF employed metals sample matrices prior spectrometric techniques.

Recent Advances in the Extraction of Polycyclic Aromatic Hydrocarbons from Environmental Samples

Molecules, Journal Year: 2020, Volume and Issue: 25(9), P. 2182 - 2182

Published: May 7, 2020

Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting two or more fused benzene rings. PAHs exhibit hydrophobicity and low water solubility, while some their members are toxic substances resistant to degradation. Due levels in environmental matrices, preconcentration step is usually required for determination. Nowadays, there wide variety sample preparation techniques, including micro-extraction techniques (e.g., solid-phase microextraction liquid phase microextraction) miniaturized extraction dispersive extraction, magnetic stir bar sorptive fabric etc.). Compared the conventional these novel show benefits, reduced organic solvent consumption, they time cost efficient. A plethora adsorbents, such as metal-organic frameworks, carbon-based materials molecularly imprinted polymers, have been successfully coupled with techniques. This review focuses on recent advances from utilizing approaches adsorbents.
