Abstract:

Chemical weapon is a kind of weapon which can attack enemy's combat power by means of poison. It can kill with many ways, large-scale, high power, and long duration. It is known as "silent killer", and its basic component is chemical warfare agents. For a long time, the use of chemical weapons in war will not only reduces the opponent's combat effectiveness, but also harms many innocent people, which is not in line with ethical requirements. Therefore, it is important to reduce the harm of chemical weapons. This article first introduces the basic knowledge of chemical weapons, including the components, classification, and then summarizes the methods of detecting and degrading chemical warfare agents in recent years from the perspective of chemistry, and prospects the development trend of decontamination technology.

Key words: Chemical warfare agents, Classification, Detection and degradation
