The Girdler sulfide (GS) process, also known as the GeibSpevack (GS) process, is an industrial production method for filtering out of natural water the heavy water (deuterium oxide. [1]

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.

It used the Girdler sulfide process to produce heavy water, and required 340,000 tonnes of feed water to produce one tonne of heavy water. It was part of a complex that included eight CANDU reactors, which provided heat and power for the heavy water plant.

 · Hydrogen sulfide is the chemical compound with the formula H 2S is a colorless gas with the characteristic foul odor of rotten eggs; it is heavier than air, very poisonous, corrosive, flammable, and explosive. Hydrogen sulfide often results from the prokaryotic breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as …

The Girdler sulfide process is an industrial production method for filtering out of natural water the heavy water, which is used in particle research, in Deuterium NMR spectroscopy, deuteriated solvents for proton NMR spectroscopy, in nuclear reactors (as a coolant and moderator) in which case they are termed ''heavy water reactors'' and in ...

The Girdler sulfide (GS) process, also known as the Geib–Spevack (GS) process, is an industrial production method for making heavy water ( deuterium oxide), an important component of many nuclear reactors because it acts as a neutron moderator.

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. ...

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".

It used the Girdler sulfide process to produce heavy water, and required 340,000 tonnes of feed water to produce one tonne of heavy water. It was part of a complex that included eight CANDU reactors, which provided heat and power for the heavy water plant.

 · The Girdler sulfide process (GS Process) was invented independently in the early 1940s by Geib in Germany and by Spevack in the US for the Manhattan Project (). The process employs a transfer of D from water in a cold tower (30 °C) to that in a hot tower (130 °C) mediated by a closed loop of gaseous hydrogen sulfide.

Heavy water is dideuterium oxide, or D 2 O or 2 H 2 O. It is chemically the same as normal water, H 2 O, but the hydrogen atoms are of the heavy isotope deuterium, in which the nucleus contains a neutron in addition to the proton found in the nucleus of any hydrogen atom. ...
