Abstract:
A process for electrochemical regeneration of basic hydrogen peroxide and chlorine for a chemical oxygen iodine laser, comprising:providing a chemical oxygen iodine laser having a singlet delta oxygen generator consuming basic hydrogen peroxide liquor and chlorine gas to produce singlet delta oxygen gas and depleted basic hydrogen peroxide liquor; providing a means for electrochemically regenerating said depleted basic hydrogen peroxide liquor into regenerated basic hydrogen peroxide and chloride reactants for use in the chemical oxygen iodine laser; providing a means for concentrating the regenerated basic hydrogen peroxide, wherein the regenerated basic hydrogen peroxide is concentrated by the removal of water therefrom; providing a means for delivering the concentrated regenerated basic hydrogen peroxide and chlorine to the chemical oxygen iodine laser thereby forming a loop of depleted and regenerated basic hydrogen peroxide and chlorine for operation of the chemical oxygen iodine laser; wherein said basic hydrogen peroxide is an aqueous solution of potassium hydroxide, hydrogen peroxide, and potassium chloride; wherein said depleted basic hydrogen peroxide is a basic hydrogen peroxide with reduced concentration of potassium hydroxide and hydrogen peroxide, and increased concentration of potassium chloride; wherein said regenerated basic hydrogen peroxide is a basic hydrogen peroxide with increased concentration of potassium hydroxide and hydrogen peroxide, and decreased concentration of potassium chloride over that of said depleted basic hydrogen peroxide; wherein the regenerated basic hydrogen peroxide has a molar ratio of H2O2/KOH at least about 1.
