What is it about?
A chlor-alkali plant drains a substantial amount of brine solution due to the presence of chlorate in it. The chlorate is produced via a side reaction occurring in the electrolysis chamber. This paper proposes a method of reducing the chlorate so that less brine needs to be purged from the chlor alkali plant. Less pollution, and higher efficiency results. Brine is the raw material for the electrolysis process.

Why is it important?
Chlorate is harmful to some aquatic life forms and have been reported to have wiped out some strains of algae. It is not readily reduced in nature, so it is important that it is reduced or its release to the environment should be eliminated. This paper suggests how it can be converted into valuable products as well.
