“…Sample agitation affects the extraction efficiency since it facilitates the mass transfer process, enhances the extraction kinetics, and reduces the sorption time. 2 So, the sample solution was stirred at 200.0-1000.0 rpm to assay the sample agitation effect. Fig.…”

“…In this regard, upper limits of pesticide residue levels are determined for agricultural purposes by respective authorities. [1][2][3] Among various pesticides, organophosphorus insecticides (OPPs) and herbicides have been mentioned as priority compounds by European legislation since long-term exposure to such highly toxic pesticides contributes to congenital disabilities, memory loss, depression, and different types of cancer. [4][5][6][7] Abundant use of pesticides, which jeopardizes the state of human well-being, has increased the demand for high-throughput, simple, and rapid analytical methods to measure the residual levels of pesticides in environmental and food samples.…”

Polyaniline nanofiber films were fabricated on the surface of stainless steel wire via a controllable and simple electrophoretic deposition route from a nonaqueous colloidal suspension consisting of polyaniline nanofibers. The prepared coating material was then characterized by field emission scanning electron microscopy equipped with energy dispersive spectroscopy and elemental mapping analysis. The fabricated polyaniline film-coated stainless steel wire was then utilized as an effective and novel sorbent phase for solid-phase microextraction of tamoxifen for subsequent gas chromatography/flame ionization detection of this anticancer drug. Parameters consisting of the temperature, extraction time, salt concentration, agitation speed, pH, temperature and time of desorption were studied and optimized using a one-at-a-time strategy. Under the optimum conditions, detection limit (S/N = 3), the limit of quantification (10/3 limit of detection), linear dynamic range, repeatability and reproducibility values of 0.51 μg L À1 , 1.7 μg L À1 , 2-1,130 μg L À1 , 5.7% and 8.6% were attained, respectively. The prepared fiber can preserve 90% of its efficacy after 20 consecutive cycles, demonstrating the suitable thermal stability and cyclability of the proposed solid-phase microextraction coating material for the determination of tamoxifen by gas chromatography/flame ionization detection. The route was effectively utilized to determine tamoxifen in urine samples, with relative recoveries ranging from 89 to 106%.

“…Solid-phase extraction (SPE), a sample pretreatment method, has been widely used to pretreat pesticides, antibiotics, and other chemical products [ 6 , 7 , 8 ] due to its excellent advantages, such as high efficiency and easy operation [ 9 ]. Additionally, the adsorption efficiency of SPE mainly depends on the interactions between packing adsorbents and analytes [ 10 , 11 ].…”

Cu-doped boron nitride nanosheets (Cu-BNNS) were first reported as promising adsorbents for the solid-phase extraction and determination of rhodamine B (RhB) dye in a food matrix. Different characterizations, including XRD, FTIR, XPS, SEM, and TEM, were performed to confirm the formation of the adsorbent. Then, the adsorption performance of Cu-BNNS was investigated by adsorption kinetics, isotherms, and thermodynamics. Multiple extraction parameters were optimized by single-factor experiments. Under optimized conditions, the recoveries in the food matrix were in the range of 89.8–95.4%, with the spiked levels of 100 ng/mL and 500 ng/mL, respectively. This novel system was expected to have great potential to detect RhB in a wide variety of real samples.
