Application of solvent extraction in the preparation of metal nano- and microparticles

Abstract

The extraction of silver, nickel, copper, and bismuth from a solution of their salts by solutions of caprylic, 2-ethylhexanoic, and Versatic 10 and 913 acids in different diluents has been studied and the possibility of obtaining concentrated solutions of carboxylates of these metals has been shown. It has been established that the nature of carboxylic acid significantly affects the extraction of silver. The process of the thermal decomposition of metal-containing organic phases prepared as a result of the extraction of silver, nickel, copper, bismuth, lead, and cadmium by a solution of carboxylic acid in benzyl alcohol has been studied. The possibility of preparing metal powders of the micron and submicron size as a result of the thermal decomposition of solutions of metal-containing carboxylates in benzyl alcohol has been shown.
