The role of aerogel-based sorbents in microextraction techniques

In recent years, the application of aerogel sorbents in sample preparation techniques has increased remarkably. These materials have unique features as sorbents and have shown good results in various sample preparation techniques. These unique features include a high surface area, low density, high porosity, and thermal stability, which make aerogels suitable as sorbents in analytical applications. In addition, it is well known that the efficiency of microextraction techniques mainly depends on the extraction material. Aerogel sorbents have been considered as suitable options to improve extraction and sample preparation techniques for different compounds present in complex matrices. This review focuses on microextraction techniques loaded with aerogel sorbent for the sampling and analysis of different compounds. In this review, the distinctive properties of aerogel sorbents in microextraction techniques are examined, with a discussion of their future prospects.
