Screen-printed carbon electrodes (SPCEs) modified with cerium oxide (ceria) have attracted considerable attention due to their outstanding stability and electrochemical performance, making them promising candidates for sensor and biosensor applications. However, the anodic electrodeposition of ceria on SPCEs involves multiple parameters that may strongly influence film formation and electrochemical behaviour, yet these factors have not been systematically optimized. This study aimed to determine and optimize the key parameters affecting anodic electrodeposition of ceria on SPCEs using cyclic voltammetry (CV) and response surface methodology. All four main parameters, namely UV irradiation time, distance between the SPCE and UV lamp, cerium nitrate concentration and the number of CV cycles, significantly influence the anodic electrodeposition process of ceria, shown by the statistical analysis (p
