Title:
Osmium from chloride solution, iridium, platinum, gold, or a solvent extraction separation method of mercury
Document Type and Number:
Japanese Patent JP6061335
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for extracting and separating a solvent of a novel metal, capable of efficiently extracting and separating noble metal elements from a hydrochloric acid solution with easy processes and operations.SOLUTION: A method of extracting and separating a solvent of a novel metal uses methylimino-N,N-bis dialkyl acetamide represented by the following general formula (I): CH-N-(CHCONR), where R represents an alkyl having 8 to 12 carbon atoms. Further, a noble metal is extracted and separated from a hydrochloric acid solution by passing the hydrochloric acid solution containing the noble metal through a noble metal extraction column containing a resin impregnated with the methylimino-N,N-bis dialkyl acetamide as extraction medium. A noble metal is osmium, iridium, platinum, gold or mercury.
