Determination of Mn(II) and Mn(VII) in beverage samples using magnetic dispersive micro-solid phase extraction coupled with solidified floating organic drop microextraction followed by graphite furnace atomic absorption spectrometry

Recent overview of microextraction of metal ions and pharmaceuticals by solidified floating organic drop microextraction techniques

“…The choice of organic solvent determines the selectivity and efficiency of analyte extraction [17]. The extraction solvent has low volatility, solubility, toxicity, and, density less than that of water, and a melting point close to room temperature (10–30°C) [43]. Many extraction solvents can be chosen for use, such as 1‐dodecanol, 1‐undecanol, 1‐bromohexadecane, n ‐hexadecane, p‐xylene, 1,10‐dichlorodecane, etc., among these, 1‐dodecanol and 1‐undecanol are more frequently used [18, 44].…”

Latest Improvements and Expanding Applications of Solid-Phase Microextraction

“…In this strategy, the N,N-dimethylcyclohexylamine has been used as extraction solvent, and the sodium hydroxide solution (10.0 M) has been employed as the phase separation trigger . The DMSPME has been also coupled with gas–liquid microextraction (GLME), dispersive liquid–liquid microextraction (DLLME), and solidified floating organic drop microextraction (SFODME) . The pretreatment approach of DMSPME-GLME has sufficiently eliminated coextracted lipid interferences and successfully achieved multiresidue pesticide analysis in fatty foods of animal origin.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…Although this approach is limited in the number of species that can be determined, it has the advantages of (a) avoiding the inherent dilution of an HPLC procedure, and (b) consenting the possible use of measurement techniques other than ICP-MS. Such procedures include the determination of iAs species in shrimp, 63 iAs in dairy products, 64 As III in water, urine and fruit juice, 65 Cr III in tap water, 66 Mn species in beverages, 67 iSb in rice wine, 68 iSe species in dairy products, 69 Se IV in foods, 59 and V V in water. 70…”
