This product is mainly used as a filter absorber in air inlet systems to filter out harmful aerosol and absorb toxic vapor, and reduce the concentration of poisoned air outdoors.
Activated carbon, when impregnated with metals such as iron (Fe), copper (Cu), chromium (Cr), and silver (Ag), becomes a crucial raw material used in protective equipment against chemical warfare.
To characterize this impregnated activated carbon, researchers employ advanced techniques such as:
Synchrotron Radiation Facilities: These include micro-beam X-ray fluorescent spectroscopy (μ-XRF), soft X-ray absorption spectroscopy (SXAS), and X-ray absorption spectroscopy (XAS). These methods help analyze the elemental distribution of metals within the activated carbon.
Scanning Electron Microscope (SEM) Coupled with Dispersive Energy X-ray Fluorescence Spectroscopy (EDS): This combination allows researchers to examine the structure and elemental composition of the impregnated activated carbon.
The results reveal the presence of various metals, particularly chromium, iron, and copper, each with distinct elemental distributions. Notably, some samples even contain Cr (VI), a carcinogen.
In summary, activated carbon plays a critical role in safeguarding individuals against chemical threats, and its impregnation with specific metals enhances its protective capabilities.
