What is the role of activated charcoal in gas masks?
Advertisements
उत्तर
The activated charcoal containing gas masks are used by coal miners to protect them from the suffocating gases and particulate matter or ashes present in the coal mines. The activated carbon binds the materials by van der waal forces. Thus, chemical compounds with large molecules, large molecular weight and insolubility are easily absorbed.
