Mechanism of Unstable Chemical Pollutants Removal with Nanocomposite Materials on Activated Carbon of Respiratory Filter
Abstract:   (1996 Views)

Introdution: The threat of chemical and biological agents both in military and in civilian is inevitable. The respiratory protection method for civilian and military people is very important when they expose to such agents.

Methods: This two military activated carbon called ASC-pyridin containing Cu (II), Cr (VI), Ag (I), pyridine and ASZMT-TEDA contains Cu (II), Ag (I), Zn (II), Mo (VI) and TEDA are studied to neutralize the unstable toxic chemical agents.

Results: Unstable chemical agents such as cyanogen chloride, hydrogen cyanide, cyanogen bromide, arsine, chlorine, phosgene and diphosgene (because of high vapor pressure and low physical adsorption on activated carbon of breathing filter) are considered a potential threat. Added transition metals salts and amines to activated carbon, could improve neutralization of unstable agents.

Conclusion: There are two kinds of military activated carbon for neutralized of unstable toxic chemical agents. ASC-pyridin military activated carbon, due to the Cr (VI) has carcinogenic properties.Then its uses has been limited and ASZMT-TEDA carbon is used widely in respiratory filters. In this type Zn (II), Mo (VI) replaced by Cr (VI) that solved the mentioned problems without reducing efficiency
