Oxygen determinations with the aluminium corrosion electrode.
A method for the determination of molecular oxygen in a great variety of liquid and gaseous samples has been developed. The method seems adaptable for control analysis by reason of its sensitivity, rapidity and ease of operation. It gives accurate determinations in the presence of many chemical substances which interfere with other methods. It is based on the variation in corrosion potential of the aluminium electrode, caused by oxygen, and exemplifies use of the corrosion phenomenon in analytical chemistry.
