ABSTRACT:
There is disclosed a process of disposing of lead azide by subjecting lead zide to electrolysis in an aqueous alkali electrolyte to recover metallic lead at the cathode. The electrolyte contains, on a weight basis, from about 10% to 20% sodium hydroxide and preferably from about 0.2 % to about 0.6% rosin powder and about 5% sodium-potassium tartrate. The preferred reaction temperature is about 180.degree. F. The preferred voltage is about 2 to 8.5 and the preferred current density is about 0.085 amperes per square inch of electrode. The preferred process results in the destruction of about 25 to 30 pounds of lead azide per hour.
