ABSTRACT Synthesis of CuO nanoparticles by hydrothermal technique in presence of cetyltrimethylammonium bromide (CTAB) as surfactant was carried out by statistically designed experiments based on Box Behnken method. Reaction parameters as time, temperature and surfactant concentration have been studied to show their effect on CuO particle size and morphology. The results of experimental design indicate that the surfactant concentration, reaction time and temperature were significant in. CuO particles were characterized using XRD and SEM. These work findings showed that CuO nanoparticles were formed at 100oC. On other hand, their crystallinity was improved with rising temperature from 100 to 200oC to achieve particle size of CuO in the range of 49-92 nm.
