“…(Perestrelo et al, 2019). Subsequent analyses have been mostly performed by gas chromatography (GC) (Pastor-Belda et al, 2015;Redondo et al, 1996;Salemi et al, 2013;Zhao et al, 2018), and liquid chromatography (LC) usually tandem coupled to mass spectrometry (LC-MS/MS) (Silva et al, 2019;Zhang et al, 2011).…”

“…In recent years, it has attracted great attention in the purification process with the advantages of good chemical stability, high surface area, strong adsorption capacity, wide application range of pH value and low cost [47,48,49]. Multi-walled carbon nanotubes (MWCNTs) [50,51,52] and magnetic amino (m-MWCNTs-NH 2 ) [53] or amino (MWCNTs-NH 2 ) [20] modified multi-walled carbon nanotubes are extensively used as sorbent materials for dispersed solid phase extraction in the detection of multi-pesticide residues. Sin-QuEChERS Nano purification column is a new sample preparation product based on the QuEChERS method.…”

A multi-residue method for the determination of 107 pesticide residues in wolfberry has been developed and validated. Similar pretreatment approaches were compared, and the linearity, matrix effect, analysis limits, precision, stability and accuracy were validated, which verifies the satisfactory performance of this new method. The LODs and LOQs were in the range of 0.14–1.91 µg/kg and 0.46–6.37 µg/kg, respectively. The recovery of analytes at three fortification levels (10 µg/kg, 50 µg/kg, 100 µg/kg) ranged from 63.3–123.0%, 72.0–118.6% and 67.0–118.3%, respectively, with relative standard deviations (RSDs) below 15.0%. The proposed method was applied to the analysis of fifty wolfberry samples collected from supermarkets, pharmacies and farmers’ markets in different cities of Shandong Province. One hundred percent of the samples analyzed included at least one pesticide, and a total of 26 pesticide residues was detected in fifty samples, which mainly were insecticides and bactericide. Several pesticides with higher detection rates were 96% for acetamiprid, 82% for imidacloprid, 54% for thiophanate-methyl, 50% for blasticidin-S, 42% for carbendazim, 42% for tebuconazole and 36% for difenoconazole in wolfberry samples. This study proved the adaptability of the developed method to the detection of multiple pesticide residues in wolfberry and provided basis for the research on the risks to wolfberry health.

“…While RM takes a relatively longer time, it is less expensive than QM. Recent studies have exhibited recoveries from sediment and soil ranging from less than ~ 40 to over 100% (Nannou et al 2018; Miyawaki et al 2018; Zhao et al 2018). Previous results showed that depending on the compound and extraction process involved, the recoveries percentages change considerably (Vagi et al 2007; Weber et al 2004).…”

Development of extraction and detection method for fluridone in water and sediment by HPLC-UV

et al. 2019

Fluridone is widely used as a herbicide for controlling invasive aquatic plants such as hydrilla in surface water bodies. When applied on surface waters fluridone can attach to bed sediment, requiring rigorous extraction methods prior to analysis. Currently, very limited information exists in terms of fluridone residue detection in delta sediment. In this study, we researched fluridone detection in both water and sediment. To extract fluridone from sediment, here we have tested two extraction methods: (1) a rotavapor method (RM); and (2) a quick, easy, cheap, effective, rugged and safe (QuEChERS) method (QM). The extraction results of RM were compared with those of QM. To quantify fluridone concentrations in extracts, a high-performance liquid chromatography (HPLC)-UV detector was used. HPLC separation was achieved using an Allure C18 5 µm 150 × 4.6 mm column with a mobile phase composed of acetonitrile and water (60:40, v/v). The UV detector was operated at 237 nm. The method was tested and validated using a series of water and sediment samples taken from Sacramento–San Joaquin Delta in California. The average recovery of fluridone was 73% and 78% using RM and QM respectively. The proposed method can be used for testing fluridone in water and sediment samples.
