“…Nowadays, the main uses of neat MOFs in analytical chemistry range from analytical sample preparation (as novel sorbents) to chromatography (as novel stationary or pseudo-stationary phases) and sensing (as novel materials in the sensors) [13]. In the majority of these applications, the GAC requirements [72] cover partially by incorporating the MOFs in microextraction approaches within sample preparation, by requiring quite low amounts of MOFs when preparing the chromatographic phases, or by incorporating minimum amounts of MOFs in the sensors. In few applications, it is also possible to find many GAC aspects fulfilled, that is: green MOF designed, MOF as prepared following a green synthesis and demonstrating low cytotoxicity, plus incorporation in a miniaturized method [54].…”

Metal-organic frameworks (MOFs) are porous hybrid materials composed of metal ions and organic linkers, characterized by their crystallinity and by the highest known surface areas. MOFs structures present accessible cages, tunnels and modifiable pores, together with adequate mechanical and thermal stability. Their outstanding properties have led to their recognition as revolutionary materials in recent years. Analytical chemistry has also benefited from the potential of MOF applications. MOFs succeed as sorbent materials in extraction and microextraction procedures, as sensors, and as stationary or pseudo-stationary phases in chromatographic systems. To date, around 100 different MOFs form part of those analytical applications. This review intends to give an overview on the use of MOFs in analytical chemistry in recent years (2017–2019) within the framework of green analytical chemistry requirements, with a particular emphasis on possible toxicity issues of neat MOFs and trends to ensure green approaches in their preparation.

“…However, in the last decade, efforts have been devoted to the development of new materials to be used as "greener" extraction phases. The green aspects of these alternative materials contribute to a less harmful and lower-cost analysis [3]. Furthermore, their usage reinforces the environmentally friendly character of microextraction techniques.…”

The use of green extraction phases has gained much attention in different fields of study, including in sample preparation for the determination of organic compounds by chromatography techniques. Green extraction phases are considered as an alternative to conventional phases due to several advantages such as non-toxicity, biodegradability, low cost and ease of preparation. In addition, the use of greener extraction phases reinforces the environmentally-friendly features of microextraction techniques. Thus, this work presents a review about new materials that have been used in extraction phases applied to liquid and sorbent-based microextractions of organic compounds in different matrices.

“…In accordance with the current trends in analytical chemistry and green analytical methodologies [15], novel strategies are gradually being incorporated in IL‐based microscale extraction approaches for the additional increase of the sample throughput while ensuring the performance of the analytical process in an unsupervised mode. These strategies utilize different tools, such as tailor‐made extraction devices and parallel extraction [16,17] or magnetic separation [18].…”

Ionic liquids and derivatives-mainly polymeric ionic liquids and magnetic ionic liquids-have been extensively used in microscale extraction over the past few years. Current trends in analytical sample preparation gear toward linking microextraction approaches with high-throughput sample processing to comply with green analytical chemistry requirements. A variety of high sample throughput strategies that are coupled to both ionic-liquid-based solid-phase microextraction and ionic liquid-based liquid-phase microextraction are herein reported. The review is focused on microscale extraction methods that use (i) custom-made and dedicated extraction devices, (ii) parallel extraction, (iii) magnetic-based separation, and (iv) miniaturized systems employing semi-automatic or fully automatic flow injection methods, related micro/millifluidic devices, and robotic equipment.
