Titanium Dioxide Nanoparticles Modified Carbon Paste Electrode for Redox Process Application

TiO2-NPs were synthesized by the SolGel procedure and characterised using a mixture of graphite powder and paraffin oil to create a homogeneous black-sensitive Titanium dioxide nanoparticle carbon paste electrode (TiO2-NPs-CPE). The best conductivity was studied by using a variety of mixture ratios, 30:70, 50:50 and 70:30, and the results refer to 50:50 as the best TiO2: graphite mixture ratio. The Redox processes were applied by Potentiostat cyclic voltammetry to mutate the trace current by electron migration. Scan rate, temperature and pH conditions studied and the result recorded (0.1 vs–1, [288-308] K and 6-7) respectively, is the best condition for electrode determination. (LOD) and (LOQ) selected with a high aquic calibration curve range (1-10) ppm used for detecting the unknown titanium ions solutions, and physical parameters (DG, DH, DS and K) were calculated (1.5, 1.2, 3.1 and 0.1) respectively (DG, DH, DS and K
