Ability of manufactoring for metal nano solution byanodic dissolving process with ultra-high dc voltage

  • Nguyễn Đức Hùng

Abstract

The process of dissolving metal anodes of Ag, Cu, Al, Fe with a ultra-high DC voltage is capable of forming nano-solution. The TEM images showed that size of metal particles is smaller than 100 nm with spherical or cylindrical shape, and they are easy to tend to aggregate into clusters of size > 100 nm, as estimated by particle distribution curve. Content of the nano-solution obtained by dissolving the anode can be determined by such methods as: AAS analysis, calculation from weight loss of soluble anode and calculation from dissolving current via Faraday's law. The solution of the metal nanoparticles obtained from the concentration of 0.27 mg / l to 3.25 mg / l. Performance of soluble anode process with high voltage direct current power is low, due to the processes to heat water and to make it dissociated to form gas on the electrodes. This gas may participate in the process of forming metallic nanoparticles in aqueous solution.
