“…Meanwhile, chemically modified polymer‐based sorbents allow the retention of nonpolar and polar compounds through Van der Waals, lipophilic, and hydrophilic interactions . The preconcentration step has been easily coupled to an on‐line separation technique, such as HPLC, by automated flow analysis systems . The automation via flow‐based devices provides the following advantages: low reagent and sample consumption, simplicity, high frequency of analysis, short duration, and less error .…”

An automated method for the analysis of methylparaben, propylparaben, benzophenone‐3, and benzophenone‐4 in water effluents via on‐line solid‐phase extraction coupled with high‐performance liquid chromatography/ultraviolet detection was proposed. The preconcentration parameters were studied using Plackett‐Burman and Box‐Behnken experimental designs using a C18 sorbent material. The results demonstrated that the eluent volume, composition, and sorbent amount were statistically significant. Optimal conditions for these variables were an eluent volume of 1.55 mL, eluent composition of acetonitrile 100% v/v, and sorbent amount of 100 mg. The eluted sample was analyzed on‐line using high‐performance liquid chromatography equipped with a reversed‐phase C18 column and ultraviolet detection. Separation of the analytes was achieved in 15 min using gradient elution with acetonitrile/water. A simple, sensitive, and rapid analytical method was proposed for personal care compounds without sophisticated or expensive equipment. The limits of detection were 1.20, 1.73, 2.51, and 4.67 μg/L for propylparaben, methylparaben, benzophenone‐3, and benzophenone‐4, respectively. The analysis time was 48 min, consuming only 1.59 mL of eluent acetonitrile for the solid phase extraction step, with minimal sample handling. The method was applied to the analysis of spiked swimming pool and wastewater, with recoveries between 65–107%. These results indicate the reliability of the flow‐based procedure.

“…5 Pyriproxyfen and fenoxycarb are two new insecticides of the class juvenile hormone analogs; their characteristics include high efficiency, low dosage, and long duration. 2,6,7 RH-5849, tebufenozide, methoxyfenozide and chromafenozide are new generation of diacylhydrazide IGRs and ecdysone analogs. They mainly induce lepidoptera pests to molt and mature prematurely by reducing or inhibiting the feeding ability of larva and adult, resulting in incomplete development of insects and reduction in oviposition; thus, the pests die in a few days, thus achieving insecticidal effect by hindering insect reproduction.…”

The aim of this work was to develop an efficient method for the selective extraction and analysis of fenoxycarb, a carbamate pesticide, in mussel samples using a molecularly imprinted solid‐phase extraction device. The optimization of molecularly imprinted polymer synthesis was performed using the experimental design under the response surface methodology approach. A fast rebinding study and Freundlich isotherm adsorption were carried out to calculate binding capacity B, site number n, and affinity constant Kf. The optimum molecularly imprinted polymer was successfully used as sorbent of a solid‐phase extraction cartridge for the determination of fenoxycarb in real mussel samples. The range of linearity was 0.3–30 mg/L with a correlation coefficient of 0.991. The limit of detection was 0.247 mg/kg. The recovery of fenoxycarb extracted from mussel samples of Mediterranean sea was 97% (n = 3) with relative standard deviation between 6 and 7% proving the reliability of the developed method.
