“…The chemistry between adsorbents and analyte properties must be considered to ensure a good adsorbent–adsorbate interaction. C18‐bonded silica , magnetite , and zeolite are some of the commonly used adsorbents that offer diverse properties for the extraction of different kinds of analytes in many applications such as biomedical field , food analysis , etc. .…”

The efficiency of the extraction and removal of pollutants from food and the environment has been an important issue in analytical science. By incorporating inorganic species into an organic matrix, a new material known as an organic-inorganic hybrid material is formed. As it possesses high selectivity, permeability, and mechanical and chemical stabilities, organic-inorganic hybrid materials constitute an emerging research field and have become popular to serve as sorbents in various separaton science methods. Here, we review recent significant advances in analytical solid-phase extraction employing organic-inorganic composite/nanocomposite sorbents for the extraction of organic and inorganic pollutants from various types of food and environmental matrices. The physicochemical characteristics, extraction properties, and analytical performances of sorbents are discussed; including morphology and surface characteristics, types of functional groups, interaction mechanism, selectivity and sensitivity, accuracy, and regeneration abilities. Organic-inorganic hybrid sorbents combined with extraction techniques are highly promising for sample preparation of various food and environmental matrixes with analytes at trace levels.

A method for the determination of aflatoxin B1 was validated according to criteria by SANTÉ 11945/2015. The samples were extracted with acetonitrile and the cleaning step was not performed. Quantification was made by liquid chromatography with fluorescence detector and pre-column derivatization with trifluoroacetic acid. No matrix effect was observed and linearity was obtained in the range of 5-80 µg L-1. The recoveries ranged from 73% to 85% with a coefficient of variation of less than 5%. The quantification limit was 6 µg kg-1 and the measurement uncertainty was ± 0.18 µg kg-1 for this level. This method was applied to 14 real samples purchased in the local market and contamination was found in one sample above the limit tolerated by the legislation (59 µg kg-1). It is a low cost method with good sensitivity and easy to execute.
