Abstract
The present invention enables simple production of osmium tetroxide having comparable performance to that sold in reagents from a solution containing osmium. The present invention relates to a method for producing osmium tetroxide solution, the method comprising a step for using ozone or a similar oxidizing gas to oxidize a solution containing osmium and produce osmium tetroxide gas and a step for introducing the resulting osmium tetroxide gas into a recovery solution; the present invention further relates to a production apparatus therefor.
Claims23
A method of producing osmium (VIII) oxide gas, comprising a step of oxidizing a waste liquid containing osmium and organic materials using ozone.
A device for producing an osmium (VIII) oxide solution, osmium (VIII) oxide-containing solid material or osmium (VIII) oxide crystal, the device comprising an oxidation part that oxidizes osmium-containing liquid, an oxidation gas supplying part that supplies the oxidation part with ozone, and a recovery part that recovers osmium (VIII) oxide gas generated within the oxidation part.
