How do you extract chlorine from sea water?

Answer 1

Ah ha I am back with a better answer.

In the past all of the heavy water for Canada's domestic and export needs has been extracted from ordinary water, where deuterium occurs naturally at a concentration of about 150 ppm (deuterium-to-hydrogen). For bulk commercial production, the primary extraction process to date, the "Girdler-Sulphide (G-S)" process, exploits the temperature-dependence of the exchange of deuterium between water and hydrogen-sulphide gas (H2S). In a typical G-S heavy-water extraction tower, ordinary water is passed over perforated trays through which the gas is bubbled. In the "hot section" of each tower the deuterium will migrate to the hydrogen-sulphide gas, and in the "cold section" this deuterium migrates back into cold feedwater.

Answer 2

one method is to use a centrifuge to separate out the heavy water and the light water.

Then use electrolysis to on the heavy water to separate out deuterium and oxygen

I'm sure there are many ways though, maybe fractional distillation methods could do the first step as the mass difference is a decent proportion of the molecular mass

I found this site as I am actually looking for the answer so maybe I'm not the best source. I am actually looking for the cheapest method, if any one knows

Answer 3

Chlorine can be extracted from sea water through a process called electrolysis. In this process, an electric current is passed through the sea water, causing the chloride ions to react and form chlorine gas, which can then be collected. This method is commonly used in the industrial production of chlorine.
