Question

Why is wood charcoal used in water filters and gas masks?

Answer 1

The incomplete combustion of plant or animal materials produces charcoal. Charcoal is mostly used for outdoor cooking. Activated charcoal, the second most common form of charcoal, is used in industrial applications.

Complete answer:
Because of its great adsorption capability, wood charcoal is used in water filters and gas masks. It is used to adsorb hazardous gases as gas masks. Because it is porous, it is used to filter water.
Wood charcoal has a porous surface that can absorb liquids and gases. As a result, it's found in water filters, gas masks, and anti gastric tablets, capsules, or powder for indigestion sufferers. Because of its ability to absorb colour, wood charcoal is also used as a decolorizing agent.
Wood charcoal can combine with oxygen in the air at room temperature, which is why some occurrences of spontaneous combustion of wood charcoal occur. Wood charcoal discharged from furnaces and retorts has a moisture level of $2-4 \%$ . The moisture content rises to $7-15 \%$ during storage. The ash content of charcoal should not exceed $3 \%$ , and the volatile content should not exceed $20 \%$ . The low level of admixtures like phosphorus and sulphur in wood charcoal distinguishes it from other types of charcoal, making it indispensable in specific metallurgical operations.

Note:
So, while charcoal has been used for a variety of reasons from ancient times, including art and healing, its most important usage has been as a metallurgical fuel. Chemists, gardeners, and homes all benefit from wood charcoal. The science of charcoal has been researched for almost 200 years, as may be seen, but there is still more to discover.
