- Nitrous oxide gas (N₂O) is produced by the radiolysis of aqueous nitrate or nitrite solutions in the presence of organic compounds. When ethylenediaminetetraacetic acid (EDTA) or N- (2-hydroxyethyl)-ethylenediaminetriacetic acid (HEDTA) is present, the G-value for hydrogen increases and N₂O become the major gaseous product (G=0.54). A survey of organic compounds indicates the amount of N₂O formed depends on the structure of the organic. With highly oxidized organics (carbonate, formate, acetate and oxalate), little or no N₂O is formed. Aromatic and aliphatic organics (sodium tetraphenylborate, benzene, phenol, n-paraffin, and tributylphosphate) produce small amounts of N₂O. Water soluble, easily oxidized organics (methanol, ethanol, isopropanol, n-butanol, acetone, and ethylene glycol) produce large amounts of N₂O relative to the previous two categories. Nitrous oxide production is not greatly affected by pH between neutral and pH=13, but increases significantly in acid solution. The G-value for N₂O production in 10 wt% potassium tetraphenylborate slurries has been measured under process conditions important at the Savannah River Site.
