A PVC membrane sensor for mercury(II) ions based on hexathia-18-crown-6-tetraone as carrier was prepared. The exhibits a Nernstian response Hg2+ over wide concentration range (1.0 × 10-3−4.0 10-6 M). It has relatively fast time and can be used at least 3 months without any considerable divergence in potentials. proposed revealed very good selectivities variety of other metal could pH 0.5−2.0. an indicator electrode potentiometric titration mercury ions.
Abstract Electro membrane extraction as a new microextraction method was applied for the of amlodipine (AM) enantiomers from biological samples. During time 15 min, AM migrated 3 mL sample solution, through supported liquid into 20 μL acceptor solution presented inside lumen hollow fiber. The driving force 200 V potential, with negative electrode in and positive solution. 2‐Nitro phenyl octylether used membrane. Using 10 mM HCl background electrolyte enrichment up to 124 times achieved....
Abstract Solvent‐assisted dispersive solid‐phase extraction (SA‐DSPE) approach was developed to measure triazole fungicides (TFs). In the SA‐DSPE technique, addition of 1000 μL ethanol as a disperser solvent, along with small quantity benzil sorbent sample solution, led cloudy solution. After completion extraction, mixture subjected centrifugation isolate benzil. Next, dissolved in ethanol, and resulting solution subsequently analyzed by gas chromatography‐flame ionization detector. This...
Abstract A sensitive, simple and reproducible method was developed for preconcentration determination of trimipramine (TPM) enantiomers in biological samples using electromembrane extraction combined with cyclodextrin‐modified capillary electrophoresis (CE). During the extraction, TPM migrated from a 5 mL sample solution through thin layer 2‐nitrophenyl octyl ether NPOE immobilized pores hollow fiber, into 20 μL acidic aqueous acceptor phase presented inside lumen fiber. Box–Behnken design...
The simultaneous extraction of acidic and basic drugs from biological samples is a significant challenge for sample preparation. A novel efficient method named dual hollow fibre electromembrane combined with CE was applied the preconcentration in single step. Under potential 40 V during extraction, ibuprofen as an drug thebaine migrated 4 mL aqueous solution at neutral pH into 20 μL each (pH 12.5) 2.0) acceptor phase, respectively; 1-octanol 2-nitrophenyl octyl ether were immobilised pores...
