In this note, the influences of each component of the eluant, namely iso-butanol, ethanol, water, and acetic acid, in the presence of oxine upon the chromatographic behaviours of the platinum metals, as well as gold and silver, have been investigated. It is found experimentally that the proper eluant should be iso-butanol, ethanol, water, and acetic acid in the volume ratio of 30:28.5:40:1.5, with an additional 1%(w/v) osinc. This eluant is good for separating mixtures of palladium-ruthenium-rhodium-gold and palladium-ruthenium-platinum-gold, etc. It has been also attempted to make clear the actions of oxine and other components. The test solutions should be buffered with dichloroacetic acid to pH 1-2.
