主权项 1. Method for producing highly pure platinum, comprising: producing a mixture comprising a nitrogen-containing hexahalogenoplatinate and water having a pH value of 0 to 4; heating the mixture to a temperature of 30° C. or higher; carrying out a reduction of the mixture at a pH value during the reduction of 0 to 4 in order to precipitate platinum in the form of a platinum sponge.
