Iron Sponge is a process that uses iron oxide to remove hydrogen sulfide gas. This process stops the corrosion of iron and replaces it with a protective coating of iron oxide. The media where the Iron Sponge is applied is lined with an absorbing layer in order to trap sulfur gasses. If you are looking for a cost-effective method of removing these gasses, read this article on Iron Sponge Process.

As for the Iron Sponge Process, you will need 3 items to complete it. You will need a 2-liter beaker with a capacity of about 0.4 gallons (1 liter) and a mesh bag of iron oxide powder. The mesh bag fits well within the glass beaker and the iron oxide is pulverized into fine powder. The glass beaker is then filled with water and this process starts by heating up the water to boiling point (100 degrees Celsius), which breaks down the hydrogen sulfide gas molecules in the water molecules and makes them more susceptible to being absorbed by the Iron Sponge.
Once this happens, it leaves behind oxidized iron particles that have absorbed much of the sulfur gas molecules in the water and this results in reducing the amount of sulfur in the water by a factor of about 3.4 (from about 130 to about 84 parts per million).
A typical iron sponge has an average surface area of about 1 square foot and it can absorb up to 70% of its weight in sulfur gas at room temperature. As the iron sponge is used during several cycles, the amount of sulfur absorbed changes from when it was new to when it is worn out as shown in the graph below. An iron sponge can be made by melting hydrated aluminum sulfate (sometimes called Epsom Salts) together with potassium ferrocyanide (iron(III) salt), sodium ferricyanide, and sodium sulfate.
