Abstract The method of direct photometric determination of copper on its self-colour is usable for the solutions of silver containing free nitric acid in concentration from 4,5 to 45 g/dm3. And last ones do not bring low accuracy at measurement of optical density of the solution. The recommended wave length is 810 nanometers. This method can be used as alternative to the more expensive methods in implementation and difficult sample preparation methods.
