text: Deuterium was first prepared in pure form in 1933 by Gilbert N. Lewis, using the electrolytic method of concentration discovered by Edward Wight Washburn.
text: Deuterium was first prepared in pure form by the electrolytic method of concentration: when a water solution of an electrolyte, such as sodium hydroxide, is electrolyzed, the hydrogen formed at the cathode contains a smaller fraction of deuterium than the water, and thus deuterium is concentrated in the residue.
