초록

A process for treating a gas generating material waste containing an alkali metal azide comprising the steps of preparing an alkaline aqueous solution containing the waste, treating the alkaline aqueous solution with a gaseous stream of ozone under conditions effective to oxidize the alkali metal azide to nitrogen and alkali metal nitrate, and then recovering the nitrate.

청구항

A process for treating a gas generating material waste which contains an azide having the formula XN3, where X is an alkali metal, and a water insoluble metal oxide reactable with said azide, comprising the steps of: preparing an aqueous slurry containing said waste and having a pH more than about 9; treating said aqueous slurry with a gaseous stream containing oxygen and ozone for a time, and with an amount of ozone, effective to oxidize said azide to nitrogen and nitrate ions in solution; and separating said metal oxide from said solution.
