• Colloidal gold
• Sodium gold(Ⅰ) sulfite
• Intra-reduction

In this study,well-dispersed gold nanoparticles were prepared by using intra-molecular reduction of sodium gold sulfite,without using additional reductants and chloride free.The technical parameters including transformation temperature,pH,and concentration were optimized by the single-factor method as 90 C,pH1,and 0.01 mmol/L[Na3Au(SO3)2],respectively.The resultant colloidal transmission electron microscopy images(TEM) and UV-vis absorption spectrophotometer spectra were acquired to check their properties,and the results show this kind of colloidal gold is controlled to 6 nm in sizes and has good stability in solution.
