“…The next step in the SPE optimization was the choice of the elution solvent. Two solvents were consideredmethanol, determined to be suitable for the elution of selected pharmaceuticals (Grujić et al 2009), and methanol-dichloromethane (1:1) mixture, efficient for the pesticide extraction (Dujaković et al 2010). At the optimal pH, the experiment was performed in the same way as previously described, using two different elution solvents.…”

“…Optimization of the water sample extraction was performed following the previously published multiresidual methods for determination of pharmaceuticals (Grujić et al 2009) and pesticides (Dujaković et al 2010) in environmental water. Solid-phase extraction was used as a proven effective method for isolation, preconcentration, and clean-up of trace amounts of pharmaceuticals and pesticides from a variety of water matrices, and Oasis hydrophilic-lipophilic balance (HLB, 200 mg/6 mL) cartridge from Waters (Milford, MA, USA) was chosen, as in the cited studies.…”

The aim of this study was the development of analytical methods for the simultaneous determination of 25 selected pharmaceuticals, metabolites, and pesticides, belonging to the various chemical classes, in river sediments and their corresponding surface and ground water with the purpose of monitoring the contamination levels. The methods were based on the solid-phase extraction as the sample preparation method for water samples, and the ultrasonic solvent extraction for the sediment samples, followed by the liquid chromatography-tandem mass spectrometry. High recoveries were achieved for extraction from both water and sediment samples for the majority of analytes. Low limits of detection were achieved for all investigated compounds in the water sample (1-5 ng L(-1)) as well as in the sediment (1-3 ng g(-1)). Applicability of the developed methods was demonstrated by determination of pharmaceutical and pesticide residues in 30 surface water, 44 groundwater, and 5 sediment samples from the Danube River Basin in Serbia. Sixty percent of target compounds were detected in environmental samples. The most frequently detected analytes in river sediments were the pesticides dimethoate and atrazine, while carbamazepine and metamizole metabolites 4-AAA and 4-FAA were the most frequently found in water samples.

The analytical procedure based on stir-bar sorptive extraction technique, for the determination of selected pesticide residues (diazinon, malathion, cyprodinyl, penconazole, fludioxonyl, pyriproxyfen, boscalid, pyraclostrobin) is described. Analysis was performed using the commercial Twister TM stir bar for sorptive extraction. It consists of a 2.0-cm-long glass-encapsulated magnetic stir bar externally coated with PDMS. The extracts were off-line analyzed using fast GC-MS in SIM mode. Optimized conditions were established as follows concerning extraction time, stirring speed, aqueous medium characteristics (ionic strength and polarity) respectively: 120 min (700 rpm), addition of 4 g of sodium chloride, no addition of methanol as organic modifier, and 30 min ultrasonic desorption in acetonitrile. Recoveries ranged from 38 % to 58 % (RSD < 15 %, n = 6). Validated limits of quantification in matrix were between 1.6 ngL −1 and 548.8 ngL −1 , depending on the compound.

“…Triazine herbicides have been analyzed using chromatographic techniques (gas chromatography (GC) and high-performance liquid chromatography (HPLC)). In the studies employing HPLC for the determination of triazines, various detectors have been used as diode array detection (DAD) (6-8, 14, 15, 18, 20, 22, 24, 25, 36, 43), ultraviolet detection (UV) (19,23,28,38,41,42,44), or mass spectrometry (MS) detection (9,10,12,13,16,21,27,30,33,40). It is important to note the advantages relating to the cost when using detection by DAD or ultraviolet (UV) compared to techniques that use MS as detector.…”

A simple, effective, and economic method for determination of nine triazines (ametryn, atrazine, cyanazine, prometryn, propazine, simazine, simetryn, terbuthylazine, and terbutryn) in drinking water based on solid-phase extraction (SPE) followed by high-performance liquid chromatography-diode array detection (HPLC-DAD) was developed. A specialized solid phase (Oasis HLB) was used, and the parameters that may affect the efficiency of SPE were optimized. The limits of detection (ranged from 0.010 to 0.023 µg L −1) were satisfactory and allow the determination of triazines at the levels required by European Union legislation. Repeatability (2.4-7.6%) and intermediate precision (0.9-11.0%) calculated at 0.1 µg L −1 (legislation level) were adequate. The accuracy calculated as the average recovery of spiked tap and mineral waters was higher than 86% for all compounds. The developed method also could be used for undergraduate laboratory experiments because it acquaints students with solution preparation, solid phase extraction procedure, and HPLC-DAD technique.
