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.
Claims3
A method of regenerating osmium (VIII) oxide solution, comprising
- a step of oxidizing a waste liquid containing osmium and organic materials using ozone to produce osmium (VIII) oxide gas, wherein the oxidizing temperature is set firstly in a range from 10° C. to 40° C., and secondly in a range from 60° C. to 100° C., and
- a step of introducing the gas into a recovery solution.
