synthesis silver nanoparticles by recovery silver from anode slime of kerman sarcheshmeh cooper complex

according to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of cu, ag, au, pb and se. in this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. silver was separated from anode slime by using of hno3 and hcl. x-ray fluorescence spectroscopy (xrf) was used to characterize anode slime components. silver nanoparticles (snps) with average size of 25 nm were obtained through sonication aqueous solution of silver nitrate in the presence of dextrose and polyvinyl pyrrolidone (pvp) as reduction and stabilizing agent respectively. snps were characterized by surface plasmon resonance (spr) and ultraviolet-vis­ible (uv-vis) spectrum. x-ray diffraction (xrd) pattern confirmed the cubic morphology of metallic snps and energy dispersive x-ray spectroscopy (eds) spectrum showed peaks of silver free of impurity. size and distribution of snps were determined by dynamic light scattering analysis (dls) and scanning electron microscopy (sem).
