Nano-sized lead oxide has useful applications that can be used in industry. In this study, the synthesis parameters were optimized using response surface methodology and ANOVA study was also carried out. Reaction temperature, sodium hydroxide and lead (II) acetate concentration were studied as the factors and the particle size was selected as the response variable. The modification was lead to increase the adequate precision of the model. Close results between R2 (correlation coefficient) and R2adj showed the accuracy of the model. The optimum results of the study were found 14.89 M NaOH concentration, 0.87 M Pb(II)Ac and reaction temperature of 88.56 °C. The particle size of lead II oxide was found to be 19.75 nm under optimum parameters.
