“…The procedure allowed the screening of an enhanced panel of analytes with comparable recovery rates and quantification limits to previously published procedures [8,11]. Taken together the proposed method can be used for routine monitoring of polar herbicide residues in real world drinking water samples in accordance with legal requirements.…”

“…Furthermore, determination of these compounds was achieved by capillary electrophoresis with ultraviolet detection (CE-UV) [5] and immunoassay methods [6]. At present, however, the most common approaches to sulfonylurea determination involve liquid chromatography (LC) with either diode array (DAD) or mass spectrometric (MS) detection [1,7,8].…”

“…Due to their low application rates, unprecedented herbicidal activity and low mammalian toxicity this class of herbicides has become very popular worldwide [1,8]. At present, 17 sulfonylurea herbicides are authorized or approved by the Federal Office of Consumer Protection and Food Safety (BVL) in Germany [2].…”

A liquid chromatographic method (LC) with diode array detection (DAD) for the routine screening and quantification of highly applicated polar herbicides in drinking water samples was developed. The investigated herbicides consisted of 12 sulfonylurea herbicides (amidosulfuron, flazasulfuron, foramsulfuron, iodosulfuron-methyl Na, mesosulfuron-methyl, metsulfuron-methyl, nicosulfuron, prosulfuron, thifensulfuron-methyl, triasulfuron and tritosulfuron) together with 6 polar pesticides of relevance (atrazine, desethylatrazine, desisopropylatrazine, chlortoluron, diuron, fluoxypyr). The herbicides were extracted and concentrated by off-line solid-phase extraction and subsequently eluates were analyzed by LC-DAD. Recoveries obtained from fortified water samples at 100 ng L -1 were in the range of 84-107% with RSD's \20%. The limit of detection varied from 2 to 16 ng L -1 .

“…To further demonstrate the purification effect of the MIL@MIP pretreatment method, 15 anonymous samples, including 5 water samples, 5 soil samples, and 5 soybean samples, were subjected to extract using MIL@MIP sorbents and assayed via the established procedure. Although no positive result was found among the collected samples, the efficiency of the presented MISPE coupled with HPLC method for spiked samples was compared with other reported methods such as HPLC/MS/MS coupled with traditional C 18 SPE [37] and HPLC method coupled with MIP-SPE [21]. In terms of LOD values and recoveries, the efficiency of this method was better than that of the two other methods.…”

A highly efficient and selective method based on core–shell molecularly imprinted polymers (MIL@MIP) and high performance liquid chromatography (HPLC) was developed and firstly used for the trace analysis of tribenuron-methyl (TBM) in complicated matrices. The MIL@MIP was prepared by surface molecular-imprinting technique, specially using MIL-101 as core, TBM as template molecule, methacrylic acid (MAA) as functional monomer, ethylene glycol dimethacrylate (EGDMA) as cross-linker, and azobisisobutyronitrile (AIBN) as initiator. The resulting MIL@MIP showed high affinity, recognition specificity, fast mass transfer rate, and efficient adsorption performance towards TBM with the adsorption capacity reaching up to 3.217 mg/g. It also showed high cross-selectivity for TBM among its six kinds of chemical structure analogues. Furthermore, using the MIL@MIP as solid-phase extraction (SPE) materials, the recoveries of TBM determined by HPLC were 84.6-92.3%, 93.3-106.7%, and 88.9-93.3% in the spiked river water, soil, and soybean samples, respectively, with the limit of detection of 0.3 ng/L, 1.5 ng/kg, and 1.5 ng/kg, accordingly. It was proved that the developed HPLC-MISPE method was fast, accurate, and sensitive for detecting the trace TBM in river water, soil, and soybean samples.

“…Analytes determination and quantitation was carried out with liquid chromatography with electrospray mass spectrometry equipped with ion trap analyzer. The recovery rates range from 76.6 to 109.1% with RSD between 0.3 to 13.8% with the HLB cartridges which was the best one of the three cartridges evaluated (Ouyang et al, 2009). Also gas chromatography, mainly with MS detection, has been extensively employed for the measurement of herbicide residues in water; different methods had been reported in the literature.…”
