Instead, sulfide combines with protons to form HS −, which is variously called hydrogen sulfide ion, hydrosulfide ion, sulfhydryl ion, or bisulfide ion. At still lower pH (<7), HS − converts to H 2 S, hydrogen sulfide. [3]Sulfides are moderately strong reducing agents.

The Girdler Sulfide process is an industrial production method for making heavy water (dideuterium oxide), an important component of many nuclear reactors because it acts as a neutron moderator.The method is a isotopic exchange process between H 2 S and H 2 O ("light" water), that produces heavy water over several steps. ...

Heavy water

The Girdler sulfide process is a method that works based on an exchange of deuterium between H 2 S and regular light water. In this process, there are two separate columns. One column is at 30°C and is known as the "cold tower" while the other one is at 130 °C, known as the "hot tower".
