“…In most cases, di(2‐ethylhexyl) phosphate (DEHP) has been used, and ionic interactions between the analyte and DEHP at the SLM interface has been found to facilitate the mass transfer . Thus, with DEHP mixed with NPOE or 1‐octanol, small cations , amino acids , peptides , and basic drugs in the log P range of –0.4 to 2.0 have been extracted successfully by EME. Clearly, with DEHP in the SLM, ionic interactions are involved, and this opens up the permeability for more polar species.…”

Electromembrane extraction was introduced in 2006 as a totally new sample preparation concept for the extraction of charged analytes present in aqueous samples. Electromembrane extraction is based on electrokinetic migration of the analytes through a supported liquid membrane and into a μL-volume of acceptor solution under the influence of an external electrical field. To date, electromembrane extraction has mostly been used for the extraction of drug substances, amino acids, and peptides from biological fluids, and for organic micropollutants from environmental samples. Electromembrane extraction has typically been combined with chromatography, mass spectrometry, and electrophoresis for analyte separation and detection. At the moment, close to 125 research papers have been published with focus on electromembrane extraction. Electromembrane extraction is a hybrid technique between electrophoresis and liquid-liquid extraction, and the fundamental principles for mass transfer have only partly been investigated. Thus, although there is great interest in electromembrane extraction, the fundamental principle for mass transfer has to be described in more detail for the scientific acceptance of the concept. This review summarizes recent efforts to describe the fundamentals of mass transfer in electromembrane extraction, and aim to give an up-to-date understanding of the processes involved.

“…The possible synergy of the AdSV technique with carbon SPEs offers outstanding advantages for electrochemical detection including the simplicity of application and high sensitivity as have been reported in several electroanalytical methods . Therefore, in this work we present a simple and sensitive electrochemical procedure using, for the first time, a carbon graphite screen‐printed electrode (SPE‐Gr) with adsorptive stripping pulse differential voltammetry (AdSDPV) for sibutramine determination in slimming tea beverages.…”

The stimulant sibutramine is an anorexic agent found as an adulterant in natural products and multivitamins supplements used for weight‐loss. In this work, a carbon graphite screen‐printed electrode (SPE‐Gr) with adsorptive stripping pulse differential voltammetry (AdSDPV) is presented for the sensitive and simple detection of sibutramine in slimming tea beverages. The proposed electrochemical method shows a linear working range from 2.0 to 120 μM with a low LOD (0.3 μM) for sibutramine determination in slimming tea samples. The analytical performance of the SPE‐Gr with AdSDPV for sibutramine detection suggests its possible application as an easy, fast and low‐cost method to analyse adulterated tea samples with this stimulant at low levels (<0.1 %).

A novel approach is presented to determine 4‐nitrobenzaldehyde in water samples. The procedure is based on switchable solvent based liquid‐liquid microextraction (SS‐LLME) and then determination by differential pulse voltammetry at multi‐walled carbon nanotubes modified glassy carbon electrode. Dipropylamine, a solvent with switchable polarity, was used as an extraction solvent that can be miscible/immiscible upon the changes of pH of sample solution. Effects of experimental conditions on SS‐LLME were investigated using a one‐factor‐at‐a‐time methodology. Under optimized conditions, a calibration curve was linear in the concentration range of 1.0 and 350 μg L−1. Limits of quantification and detection were empirically 1.0 μg L−1 and 0.3 μg L−1, respectively. Intraday and Interday RSDs%, calculated in three concentration levels, were in the range of 6.2–7.8 % confirm the proper precision of the method. Finally, the performance of the method was evaluated successfully in real samples including drinking water, tap water and river water.
