【 摘 要 】

In this study, the experimental parameters for synthesis of silver (П) oxide (AgO) particles were controlled to achieve various particle sizes with different morphology. The AgO particles were synthesised by alkaline oxidation in the presence of potassium persulfate (K 2 S 2 O 8 ). Characterisation of AgO particles was performed by X-ray diffraction, Fourier-transform infrared spectroscopy, and field emission scanning electron microscopy (FE-SEM) techniques. The analysis of FE-SEM images with Digimizer image analysis software indicated that the AgO particles were in micro and nanosize ranged from 50 to 150 nm in thickness and 0.58 to 1 µm in length. Also, pebble, slice, and flake morphologies were observed by controlling the experimental conditions. The general factorial design method was applied to investigate the effect of variable factors suchas the concentration of AgNO 3 (CAg + ), the concentration of K 2 S 2 O 8 (CS 2 O 8 2− ), and the mole ratio of AgNO 3 to K 2 S 2 O 8 (RAg + /S 2 O 8 2− ), whereas the particle size was the response to be analysed. Based on the results of the analysis of variance, the model was significant. Investigations indicated that the interaction between CAg + and RAg + /S 2 O 8 2− has a significant effect on the AgO particle size. Validation of the results showed that residual and desirability values are 2.2% and 0.935, respectively.
