FIELD: chemistry.
SUBSTANCE: method consists in the introduction of highly active raffinate of complexing agent (amino-acetic acid) forming complex compounds in the result of the coordination interaction with palladium, from which palladium is reduced to metal by the action of hydrazine.
EFFECT: group of inventions allows to selectively extract from nitrate media more than 99,3 percent of metallic palladium in the form of coarse sediment in the first version and in the form of deposits on the surface of the particles of the granular layer of solid catalyst in the second version obtaining concentrated solutions of palladium regenerated after its dissolution in nitric acid.
