Abstract: This study describes the design and constructs a selective electrochemical sensor for electroanalytical purposes. The sensor is based on the synthesis of molecularly imprinted polymer (MIP) (uranyl ion) and mixed with graphite powder in the structure of ceramic electrodes and produce (MIP) ceramic electrode (MIPCE), and used for electrochemical determination of uranyl ions. Due to the presence of empty spaces embedded in the electrode bed, uranyl ions absorbed selectively and determined by sensor. After designing the sensor, cyclic voltammetry and differential pulse voltammetry (DPV) methods were used for the studies and measurements the uranyl ions in the aqueous solution. The ceramic sensor is based on the mixing of ion imprinted polymer powder and graphite powder and showed an increased linearly response with UO2(2+) concentration in the range of 0.1 μM to 0.1 mM with a detection limit of 0.03 μM. Finally, after detecting and studying the behavior of sensor in a standard sample of aqueous solution, the sensor is effectively and selectively used to determine the uranyl ion in soil real samples without any interference. The results of this research are in this article is being reported
