The silver nanostructures obtaining was investigated by electrochemical deposition from aqueous solutions ((1…10) mM AgNO3 + 50 mМ NaPA) onto graphite substrate. The influence of the concentration of silver ions and cathodic potential values in the range E = -0,2 ... -1,0 V on surface filling degree and geometry of silver particles was (had been) studied. It is shown, the discrete silver particles ranging in size
from 50 to 400 nm with a uniform distribution on the surface of the substrate are formed. It is established that decreasing of the concentration of silver ions and increasing of cathodic potential tends to reduce the particle size.
