“…I 0 and I are the fluorescence intensity of SEF hydrosol before and after the addition of Fe 3+ at various concentrations (Figure 9). The lower detection limit (LOD) [35] of Fe 3+ was recorded to be 8×10 −9 M. The R‐square value of the linear detection range was 0.98945, implying good linearity in the calibration graph. The Fe 3+ concentration that is permissible in drinking water is 0.3 mg/L.…”

Silver nanoparticles were synthesized using alkaline salicylaldehyde (SL) in the presence of silver nitrate. SL was oxidized to quinone form, while silver(I) was converted to silver (0). The solution was highly fluorescent, (quantum yield 7 %, λ ex 290 nm, λ max 424 nm), where silver (0) exhibited metalenhanced fluorescence and quinone acted as the fluorophore. The fluorescence was selectively quenched with the addition of Fe 3 + . No other metal shows such drastic fluorescence quenching. Thus, silver-enhanced fluorescence is used to detect iron selectively and sensitively (limit of detection 2 × 10 À 9 M, linear detection ranges from 10 À 4 M to 8 × 10 À 9 M). The detection of iron was also done at various water of natural sources (drinking water tap water, rainwater, and Ganga River water). The iron concentration was quite similar to atomic absorption spectroscopy. The enhancement of fluorescence of the sliver atom is attributed to enhanced photonic mode density, related to the lightning rod effect. The quenching of silver-enhanced fluorescence was attributed to the destruction of the capping agent due to SL-iron complexation. The variation of distance between the fluorophore and metalized surface was anticipated for the alteration of fluorescence with and without the Fe 3 + ion.

In the last 10 years the interest in deep eutectic solvents (DESs) as a new class of green solvents has considerably increased. The emergence of numerous of hydrophobic DESs has stimulated intensive research into their application in extraction technologies, including sample preparation. As the properties of such systems are highly dependent on the properties of their components (hydrogen bond donors and acceptors) and can be finely tuned, DESs can be successfully used for the extraction of both metal ions and organic substances, including biomolecules. Despite the rapidly increasing number of publications on the use of DESs as an extraction medium, including review articles, information on the extraction properties of DESs in terms of their chemical composition has not yet been summarized. This review covers available literature data on the physicochemical properties of menthol‐based eutectic solvents and the results of their practical application as an extraction medium. Also, the appropriateness of using the term “DES” for all mixtures with melting points lower than the melting points of their components is discussed.

“…Sample treatment is a key step for ensuring the effective extraction and purification of different classes of drugs from animal tissue [ 19 ]. Compared to other pretreatment techniques, such as magnetic solid phase extraction (SPE) [ 20 ], solid-phase micro-extraction (SPME) [ 21 ], magnetic solid phase extraction (MSPE) [ 22 ], dispersive solid phase extraction (d-SPE) [ 23 ], pressurized liquid extraction (PLE) [ 24 ], and liquid–liquid micro-extraction (LLME) [ 25 ], the quick, easy, cheap, effective, rugged, and safe (QuEChERS) [ 3 , 26 ] sample preparation method enables higher recovery and accuracy as well as less exposure to harmful solvents. Petrarca et al [ 3 ] developed a method that the determination of 10 SAs in complex infant formula matrices by QuEChERS, which showed good linearity in the concentration range of 5–120 μg kg −1 (R 2 ≥ 0.991).…”

There were few reports about antibiotic residues in egg-containing products. In the study, an effective method for the simultaneous determination of 24 sulfonamide antibiotics in two instant pastries based on a modified QuEChERS sample preparation technique coupled with ultra performance liquid chromatography-tandem mass spectrometry was developed. The results show that the average recoveries of the SAs at 5, 10, and 50 μg kg −1 levels were 67.6%–103.8%, with relative standard deviations (RSD) of 0.80–9.23%. The limit of detections (LODs) and limit of quantitations (LOQs) were 0.01–0.14 μg kg −1 and 0.02–0.45 μg kg −1 , respectively. This method was suitable for analysis of 24 SAs in instant pastries.
