FIELD: quantum electronics. SUBSTANCE: method involves absorption of gaseous oxygen by liquid solution that incorporates reducing form of oxidizer, electrochemical reduction of dissolved oxygen up to superoxide O-
2
, electrochemical single-electron oxidation of reduced form of oxidizer, and oxidation of superoxide O-
2
by product obtained to singlet oxygen O2(1Δg) which is then passed to receiver; liquid solution contains iodine anions I- and singlet oxygen O2(1Δg) receiver is, essentially, gas phase above liquid solution surface opposite surface absorbing gaseous oxygen. EFFECT: facilitated procedure.
