“…Compared with the presented asulam determination method, the methods in Table 5 show some disadvantages in the limit of detection, 1,4,5,7,8,12,37 linear dynamic range [3][4][5]10 , and the range of the sample analyzed. [1][2][3][4][5][6][7][8][9][10]12,37 Moreover, the analytical characteristics of the presented sulfide determination method were compared with the others as shown in Table 6. Compared with the presented sulfide enrichment/determination method, the others show some limitations in the limit of detection, 19,20,38−44 linear dynamic range, 20,42 and the range of the sample analyzed.…”

This study reports 2 new simple derivatization-based dispersive liquid-liquid microextraction (DLLME) methods for spectrophotometric ultratrace determination of asulam and sulfide. 1-Naphthol (in the presence of nitrite) and N,N-diethyl-p-phenylenediamine (in the presence of Fe(III)) were used to derivatize asulam and sulfide, respectively.In the enrichment methods, the formed derivatives were preconcentrated into microdroplets of the in situ formed water insoluble ionic liquid (IL), 1-hexyl-3-methylimidazolium hexafluorophosphate. Monitoring was performed at 526 nm for asulam and at 664 nm for sulfide, after dissolution of the IL-rich phases into the basic ethanolic solution and ethanol for asulam and sulfide, respectively. Beer's law was obeyed in the ranges of 1.0-80.0 and 0.1-5.0 ng mL −1 for asulam and sulfide, respectively. Limits of detection for asulam and sulfide determination by the DLLME methods were 0.18 and 0.019 ng mL −1 , respectively. Various foreign cations, anions, organics, and pesticides were tested to evaluate the selectivity of the DLLME methods. The methods were successfully applied to the determination of asulam and sulfide in various environmental, wastewater, and urine samples.

“…C18 can result in poor recoveries of some more nonpolar GCamenable analytes (recoveries <70 or >120%) when the sample matrix has a high fat content and, under these situations, Zr-Sep+ has been used to remove lipids [15]. Zr-Sep+ was also used for cleanup of extracts from high fat content edible oil samples reducing matrix effects better than observed with PSA and C18 [23]. Activated charcoal with PSA has also been used for edible oils [24].…”

This chapter focuses on sample preparation procedures for pesticide analysis of food commodities, biological and environmental matrices. This will include pesticides with a broad range of polarity including those that are more amenable to gas chromatographymass spectrometry (organochlorines, organophosphorus pesticides, and pyrethroids) and those commonly analyzed by liquid chromatography-mass spectrometry (carbamates, azole, and strobilurin fungicides, and phenylureas as well as organophosphorus pesticides). QuEChERS (quick, easy, cheap, effective, rugged, and safe) methods or QuEChERS methods with modifications to allow wetting of the dry sample matrix, buffering, changing extraction solvent from acetonitrile to ethyl acetate are examined. Subsequent cleanup using dispersive solid phase extraction or cartridge format solid phase extraction has also been completed to reduce matrix effects. Other solid matrices are frequently extracted with pressurized liquid extraction, microwave assisted extraction, or ultrasonic extraction combined with or followed by dispersive solid phase extraction or solid phase extraction. Particularly for chromatography-mass spectrometry, careful consideration of matrix effects needs to be made when considering the design of the sample preparation procedures. Selection of extraction solvent needs to consider both polarity of target analytes (and their solubility in selected solvents) as well as co-extracted matrix components.

“…Moreover, a freezingout step prior to d-SPE has been introduced for initial clean-up of the edible oil extracts (Parrilla Vázquez et al 2016). Current developments of extraction methods based on modifications to the QuEChERS procedure were elaborated by several authors (Polgár et al 2012, Ruiz-Medina et al 2012, Moreno-González et al 2014, Parrilla Vázquez et al 2016, Dias et al 2016, He et al 2017.…”

“…Both gas chromatography (GC) (Guardia-Rubio et al 2006, López-Feria et al 2009, Deme et al 2014, He et al 2017, Parrilla Vázquez et al 2016) and liquid chromatography (LC) (Gilbert-López et al 2010, Sobhanzadeh et al 2011, Polgár et al 2012, Moreno-González et al 2014) coupled with mass spectrometry (MS), or tandem mass spectrometry (MS/ MS) detection, are widely used for the determination of pesticides in vegetable oils. Nevertheless, less selective highperformance liquid chromatography with diode array detector (HPLC-DAD) was also successfully applied to the analysis of pesticide residues in edible oils (Jaabiri et al 2013, Ma et al 2016).…”

This study develops a simple, cost-effective and sensitive high-performance liquid chromatography with diode array detector (HPLC-DAD) method for the simultaneous determination of eight sulfonylurea herbicides (oxasulfuron, metsulfuron-methyl, triasulfuron, chlorsulfuron, amidosulfuron, mesosulfuron-methyl, bensulfuron-methyl and tritosulfuron) in rapeseed oil. Extraction of target analytes was performed using quick, easy, cheap, effective, rugged and safe-based procedure followed by solid-phase extraction (SPE) and dispersive solid-phase extraction (d-SPE) cleanup, and presents good performance for all of the analytes with recoveries in the range of 67-133% and relative standard deviations (RSD) less than 15%. No significant matrix interference was observed due to the application of effective zirconium dioxide-based sorbent (Z-Sep). Method LOQs for most of the investigated analytes were set at satisfactory low value of 20 ng g −1 in food product. The procedure was evaluated in analyses of actual samples. The most important steps of the method optimization are presented. Novel EMR-Lipid cleanup solution for samples with high fat content was evaluated and compared to Z-Sep sorbent.
