From 1906 to 1913 he was director of the Muspratt Laboratory, from 1913 to 1937 he was professor of chemistry at University College London.

He is considered the co-founder of physical chemistry in England and delivered significant contributions to colloid chemistry, via osmotic processes and the theory of solutions.

In 1911 he described the Donnan equilibrium ( also Donnan effect, Gibbs - Donnan effect, Gibbs - Donnan equilibrium, Donnan law ).

After Hitler took power in Germany in 1933, Donnan intensive care to emigrate, and persecuted German scholars and gave many of them a temporary home at his institute.
