Magnetic solid phase extraction has been used as pretreatment technique for the analysis of several compounds because of its advantages when it is compared with classic methods. This methodology is based on the use of magnetic solids as adsorbents for preconcentration of different analytes from complex matrices. Magnetic solid phase extraction minimizes the use of additional steps such as precipitation, centrifugation, and filtration which decreases the manipulation of the sample. In this review, we describe the main procedures used for synthesis, characterization, and application of this pretreatment technique which were applied in food analysis.

“…On the other hand, solid phase extraction (SPE) is a separation, purification, and preconcentration method based on adsorption of target analytes onto different resins [22,23] There are two phases in the technique: stationary and mobile phases. Aqueous sample containing target analyte passes through the chromatographic column gravitationally after providing specific conditions for retention of analyte on the resin.…”

A B S T R A C TThis study deals with the preconcentration, determination, and removal of Lanaset Blue 2R textile dye from aqueous medium by two different methods. For this purpose, cloud point extraction (CPE) and solid phase extraction (SPE) methods were optimized. Amberlite XAD-1180 resin was used as adsorbent for SPE while Tergitol NP-7 non-ionic surfactant was used as surfactant rich phase for CPE. The common optimization steps were determined as initial solution pH, linear dynamic range, sample volume, equilibrium time and limits of detections were characterized for both SPE and CPE techniques while specific optimization steps such as temperature and surfactant concentration were also determined for CPE. The results showed that the CPE and SPE of dye were quantitative at pH 6. Detection limits were 21-μg L −1 for CPE and 9-μg L −1 for SPE. The enrichment factors were 40 and 10 for SPE and CPE, respectively. The real sample analysis was successfully performed with both techniques. The strengths and weaknesses of the methods were highlighted.

“…Coating material prevents magnetic nanoparticles from agglomerating; on the other hand it has been proven that some chemical or physical surface modifications of coating material have improved its selectivity and/or affinity towards special target [14]. Therefore, not only the importance of coating material in FF is not deniable but also designs and production of ferrofluid with especial coating material is currently under intensive investigation [15].…”
