A rapid and environmentally friendly analytical method based on conductive polymer as extraction phase for disposable pipette extraction for the determination of hormones and polycyclic aromatic hydrocarbons in river water samples using high-performance liquid chromatography/diode array detection

Miniaturized Salting-Out Assisted Liquid-Liquid Extraction Combined with Disposable Pipette Extraction for Fast Sample Preparation of Neonicotinoid Pesticides in Bee Pollen

“…In addition, it allows for automated and high-throughput preparation when combined with the liquid handling system [18,19]. This sample preparation method has been widely used in the analysis of drugs [14,[18][19][20][21][22][23][24], pesticide residues [16,17,[25][26][27][28][29][30], heavy metal ions [31], and environmental contaminants [32][33][34][35]. In the present work, the parameters of DPX were systematically investigated on the clean-up of neonicotinoid pesticides in bee pollen.…”

Restricted access polypyrrole employed in pipette-tip solid-phase extraction for determination of nimodipine and nicardipine in breast milk

“…15–17 Specifically, PPy and its derivatives have become one of the most used, due to their stability in air and in aqueous solution, ease of obtaining directly from pyrrole via electrochemical polymerization, oxidative polymerization or chemical vapor deposition, large surface area and good adsorption. 18,19…”

“…[15][16][17] Specically, PPy and its derivatives have become one of the most used, due to their stability in air and in aqueous solution, ease of obtaining directly from pyrrole via electrochemical polymerization, oxidative polymerization or chemical vapor deposition, large surface area and good adsorption. 18,19 Since the PPy properties of interest can be obtained by different synthesis methods, approaches by electrochemical and chemical methods of oxidative polymerization have been the most employed. In electrochemical polymerization, a pyrrole monomer is oxidized anodically in aqueous or nonaqueous solution, forming a thin lm on the surface of the electrode.…”

Fluoranthene determination based on a rapid and sensitive syringe extraction and solid‐phase fluorescence technique

“…The rapid detection of FL poses challenges due to its hydrophobic nature and low concentrations in complex matrices. Currently, gas chromatography (GC) [10][11][12][13][14][15][16] and high-performance liquid chromatography (HPLC) [17][18][19][20] are commonly used methods for FL detection. However, these methods are intricate, time-consuming in terms of pretreatments and measurements, and require large-scale instrumentation, all of which are not suitable for rapid on-site detection.…”
