Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -New chemically modified carbon paste (CPEs) and screen-printed electrodes (SPEs) were fabricated incorborating copper oxide nanoparticles (CuO NPs) as a neutral ionophore and explored as Cu(II) selective electrodes. The fabricated electrodes were satisfactory applied to determine Cu(II) ion in pure solutions and different real spiked water samples using the proposed potentiometric method. The results obtained applying MCPEs and MSPEs agree well with the inductively coupled plasma atomic emission spectrometry (ICP-AES). 100 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Spectrophotometric determination of OphC drug in pure and in pharmaceutical preparations via charge transfer complex formation between OphC (electron donor) and both of DDQ and p-CLA (pi-acceptor) reagent. The work has focused on the preparation of homemade carbon ink and testing the performance of such ink in the fabrication of electrodes for the potentiometric determination of OphC drug in pure and pharmaceutical preparations. The performance of such sensors in the Potentiometric determination of OphC is compared between those of CWE and coated graphite electrodes. 224 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The modified ISEs sensors show high selectivity and sensitivity for determination of copper(II) and iron(III) ions over the other ions. Also they showed stable and reproducible response over a period of five and three months for Copper(II) SPE and CPE sensors, respectively, and 86, 74, 66 and 95 days for Fe(III) electrodes (I, II, III and IV), respectively. This method can be used for potentiometric determination of copper (II) and iron(III) in water, soil, plant and fish tissue samples and the obtained results agreed with those obtained with atomic absorption spectrometer (AAS). Cu(II)-SPEs, CPEs and Fe(III)-CPEs showed advantages over other methods as high performance, selectivity, sensitivity in a wide range of activities, long-term stability, wide pH range, fast and easy preparation procedures, simple instrumentation, low cost and higher calibration graph slopes. 212 pp. Englisch.…
