Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Analytical Chemistry Summary: Four new ion-selective electrodes (ISEs) based on N,N'-bis- (salicylaldehyde)-p-phenylenediamine (SPD) as ionophore are constructed for determination of copper ion. The modified carbon paste (MCPEs; electrodes I and II) and modified screen printed sensors (MSPEs; electrodes III and IV) exhibit a good potentiometric response for Cu(II) over a wide concentration range of 1 {u00D7} 10⁻⁶ - 1 {u00D7} 10⁻² mol L⁻¹ (for electrodes I and II) and 4.8 {u00D7} 10⁻⁷ - 1 {u00D7} 10⁻² mol L-1 (for electrodes III and IV) with a detection limit of 1 {u00D7} 10⁻⁶ mol L-1 (for electrode I and II) and 4.8 {u00D7} 10⁻⁷ mol L⁻¹ (for electrode III and IV) for MCPEs and MSPEs, respectively. The slope of the calibration graphs are 29.6±0.9 and 30.5±0.7 mV decade-1 for MCPSs with tricresylphosphate (TCP) (electrode I) and o-.nitrophenyloctylether (o-NPOE) (electrode II) as plasticizers, respectively.Also, the MSPEs show good potentiometric slopes 29.9±0.5 and 30.7±0.3 mV decade-1 with TCP (sensor III) and o- NPOE (sensor IV) placticizers, respectively
