Résumé
As an important measure to reduce casualties and prevent secondary pollution, decontamination is an impor-tant link in the process of emergency response during chemical accidents.The decontamination effect is closely related to decontamination technology and equipment.Decontamination agent selection and development are an important part of a decontamination technology.In this paper, the development and use of cleaning agents, such as alkaline, oxidation and chlorination, adsorption (degradation), metal oxide and oxygen acid salt, chemical compounds, biological (enzymatic), and individual disinfection package, light decontamination equipment, multifunctional integrated large-scale decontamination equipment at home or abroad, are reviewed.By laying bare the gap between China and advanced countries in the related field, we hope to raise the concern of relevant professional counterparts and promote the development of domestic decontami-nation technology and equipment with decontaminant agents at the core.
