The team from the University of North Carolina at Chapel Hill has used a specially designed apparatus to test a new chemical weapons protection system that uses a chemical element called carbon.
The new device is made up of a specially manufactured tube that holds the carbon dioxide gas and the oxygen.
When the tube is filled with water, the carbon reacts with the water and forms an ion that carries the carbon to a chemical reaction chamber, where it is then broken down into hydrogen and oxygen.
The researchers tested the new system with a chemical agent that contains carbon dioxide, sulfuric acid and a mixture of other chemicals, and found that the gas-and-oxygen reaction produced enough chemicals to kill a small percentage of a human lung.
“The test is not the most reliable, but the result is still useful,” said John C. Hall, a chemical warfare expert at the U.S. Army War College.
“I think it’s important to demonstrate the safety of the system.”
