Respiratory Protection Against Hydrogen Cyanide

In-situ degradation of sulphur mustard and its simulants on the surface of impregnated carbon systems

“…This system removes gases such as hydrogen cyanide, cyanogen chloride, phosgene, etc. [5][6][7][8][9][10][11][12][13]. All of these gases are highly volatile and fall in the category of non-persistent chemical warfare agents (CW).…”

Reactions of sulphur mustard on impregnated carbons

“…These metal ions play important role in chemical degradation of HCN, CNCl, COCl 2 , etc. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Of these toxic chemicals, the degradation of cyanogen chloride depends upon the amount of chromium present as Cr(VI) on impregnated carbon.…”

Impregnated carbon for degradation of diethyl sulphide

“…One such reactive carbon developed long back is the Whetlerite carbon, i.e., activated carbon impregnated with Cu(II), Cr(VI) and Ag(I) [5]. This carbon is being used effectively for the reactive removal of the non-persistent chemical warfare (CW) agents like cyanogen chloride, hydrogen cyanide and phosgene [6][7][8][9][10][11][12]. However, in the case of persistent CW agents such as sulphur mustard (HD) and its analogues, a suitable reactive carbon is to be used in filtration systems for in situ degradation [13].…”
