Amodiaquine polymeric membrane electrode

Development of a New Coated Platinum Selective Electrode for Moxifloxacin Determination

“…The amount of MOX-TPB between 1.0 % and 2 % (w/w) was found to generate the better response. This is in agreement with the previous work [37,45]. In fact, increasing of the electroactive material over this percentage 4% (w/w) resulted in a diminished response slope of the electrode, most probably due to some inhomogeneity and possible saturation of the membrane [46].…”

“…42, washed with 100 mL distilled water, dried at room temperature for 24 h, collected, ground and kept. The MOX-TCPB ion-pair was generated "in situ" [37] at the membrane surface by preconditioning the fabricated electrode (which contains PVC, plasticizer, KTCPB) in a 1.0 × 10 -3 mol.L -1 of MOX solution for more then 48 h. The color of the membrane varies from transparent to yellow, indicating the formation of the MOX-TCPB ion-pair.…”

Research progress in electroanalytical techniques for determination of antimalarial drugs in pharmaceutical and biological samples

“…82 The sensing membrane was based on water-insoluble ion-pair complex formed between the cationic drug and NaTPB or KTCPB as the ion-exchanger. 82 The sensing membrane was based on water-insoluble ion-pair complex formed between the cationic drug and NaTPB or KTCPB as the ion-exchanger.…”

Sibutramine Selective Electrodes for Batch and Flow Injection Determinations in Pharmaceutical Preparations

“…For (Sibu)3-PT electrode the characteristics are: slope, 59.7 mV concentration decade -1 at 25 C; usable concentration range, 3.84 × 10 -5 -1.00 × 10 -2 M SibuCl; detection limit, 1.47 × 10 -5 M; response time, ≤10 s. The PVC acts as a regular support matrix for the plastic membrane ion-selective electrode, but its use requires a plasticizer which acts as a fluidizer allowing homogeneous dissolution and diffusional mobility of the electroactive complex inside the membrane. 16 Three plasticizers, DBP, DOP and DOS, were examined ( Table 2). The result indicated that DBP is the best of the plasticizers tested.…”
