ABSTRACT:
A method of detecting hydrogen cyanide using an electrochemical cell is disclosed. The cell comprises an electrolyte which is initially free of any salt capable of dissociating to form cyanide ions, a pH detection electrode and a reference electrode. A membrane permeable to hydrogen cyanide gas is used and the potential developed between the electrode is monitored as a measure of hydrogen gas partial pressure.
