  • Patent number: 9371572
    Abstract: The present invention relates to a procedure for preparation by wet reduction method of nanometric particles of metallic silver, with diameter in the range of 1 to 100 nm and an average diameter of 20 to 40 nm, with monodispersion characteristics, stability greater than 12 months and in a wide range of concentrations. The process comprises 4 steps: a) preparation of the reducing agent solution, taken from the group of tannins and preferably being tannic acid; b) preparation of a solution of a soluble silver salt; c) reaction and, d) solid-liquid separation; the particle size is determined by the nature of the reducing agent and by the pH control of the currents. The final step is designed for separating and concentrating the material after which the user can prepare the product for integration thereof in the desired medium.
