2-Amino-N-benzthioazolyl benzamide (ABTB) was synthesized, characterized and used for thefabrication of a potentiometric sensor for Cu2+ metal ions. The electrode exhibits linear response to Cu(II) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 M) with Nernstian slope of 30 ± 1.5 mVper decade. The electrode can be used in the pH range from 2 to 9. It has a fast response time of about1...

a carbon ionic liquid electrode (cile) modified with tio2-fe nanoparticles was constructed by incorporating tio2-fe nanoparticles into the paste matrix. under the optimized experimental conditions, using differential pulse voltammetry (dpv), the oxidation of thiocyanate and oxalate were occurred at potentials of 0.740 v and 1.010 v, respectively, at the surface of the modified electrode. observi...

A new voltammetric sensor for determination of uric acid (UA) by Cuppercomplex- multiwalled carbon nanotube (Cu-complex-CNT) nanocomposite modifiedcarbon paste electrode (CPE) is reported. The electrocatalytic behavior of theCu-complex-CNT nanocomposite modified CPE was studied in pH 2.0 phosphatebuffer solution by chronoamperometry (CA) and cyclic voltammetry (CV) in th...

A comparative study was made between developed chemically modified carbon paste electrodes and PVC membrane electrodes for the cationic surfactant cetyltrimethylammonium bromide (CTAB). The carbon paste electrode modified with cetyltrimethylammonium-tetrachloropalladate(II) (CTA-TClP) provides a more sensitive and stable device than that shown by electrodes with an inner reference solution. The...

in this work, modification of carbon paste electrode surface with poly (2, 5-dimethyl aniline) (p-2,5-dma) by using electrochemical polymerization was described. then, transition metal ions of ni(ii) were incorporated into the polymer film by two ways. at first way, the polymeric modified electrode was immersed in 0.2 m niso4 solutions and the second way was carried out by electrodeposition of ...

A simple electrochemical sensor consisting of electrically heated carbon paste electrode with the surface modified by dsDNA is used to characterize voltammetric behaviour and antioxidative activity of four selected flavonoids. Quercetin, rutin, catechin and epigallocatechin gallate accumulate within the DNA layer. A positive effect of the electrode temperature within the range of 20 to 38 oC on...

Titania nano particles were synthesized at carbon paste electrode by cyclic voltammetry and then it was employed for the determination of acetaminophen in phosphate buffer at pH 7.4. Carbon paste electrode with titania nano particle displayed excellent electrochemically catalytic activities by shifting the oxidation potential of acetaminophen towards the negative side. The mass transfer process...

   Significant effects of magnetic iron oxide (Fe3O4) nanoparticles on the potentiometric behavior of carbon paste electrode for bio determination of Isoniazid aromatic drug (INH) were studied. The electrochemical performance of modified Fe3O4/CPE was investigated. The constructed Fe3O4/CPE showed high precision, sensitivity ...

A chemically modified carbon-paste electrode has been described for the sensitive and selective determination of amantadine. Beta-cyclodextrin was used as modifier. The electrode shows a sub-Nernstian response of 51.0 +/- 1.0 mV decade(-1) for amantadine in the concentration range of 6.3 x 10(-10)-7.1 x 10(-7) M at 25 degrees C. The optimum pH value was maintained at 4.5 using a 0.02 M acetate ...
