Objective: To prepare the colloidal nano-silver particles and detect their characters. Methods: Positive charged colloidal nano-silver particles were prepared by sodium citrate-induced reduction of silver nitrate.The silver sols were characterized by means of transmission electron microscope and UV-Vis. Results: Maked a deeper reseachment of the adsorption character on the silver particle surface. Conclusion: Confirmed the competiting adsorption property of different molecule.
