AbstractA new poly (vinyl chloride) (PVC) membrane electrode using 2-benzoylpyridine semicarbazone as membrane carrier with dioctylphthalate as plasticizer and sodium tetraphenylborate (NaTBP) as anion excluder has been fabricated and investigated as Zn(II)-selective electrode. Best potential response is observed for the composition PVC 30%, plasticizer 58%, NaTBP 8% and ionophore 4% (w/w). The sensor showed a linear stable response over a concentration range of 1.0 × 10−2–4.56 × 10−6 M with a detection limit of 2.28 × 10−6 M and a response time <10 s. The electrode can be used for at least six months without any divergence in potential.

New, simple, sensitive and rapid method for the determination of propranolol in the pharmaceutical preparations and human fluids. The Buildup and electrochemical response characteristics of a poly vinyl chloride (PVC) selective membrane electrode for the determination of propranolol (POP) are described in this research. The proposed electrodes was composed of propranolol-bromophenol blue as ion-exchanger and Di-butyl phthalate (DBPH) (electrode A), tris (2-ethylhexyl) phosphate (TEHP) (electrode B), and ortho-nitrophenyloctylether (ONPOE) (electrode C), as plasticizers. The slope was 50.94, 57.77, and 49.75 mV/decade for electrode A, B and C. the linear range was 5 ×10-5 – 1×10-2, 1×10-4 – 1×10-2, and 5×10-5 – 1×10-2 M, a detection limit of 4.2×10-5, 8.9×10-5, and 4.8×10-5 M, lifetime of 21, 42, and 1-day, respectively. Electrode B gives the best results, so the application of pharmaceutical and human fluids was based upon this electrode, the recovery percentage was 103, 101, 102.5, and 104 for POP tablet 10mg, tablet 40mg, urine and plasma by standard addition method, respectively.
