Activated carbon was first produced on an industrial scale at the beginning of the twentieth century. During World War I activated carbon was used in gas masks worn by American soldiers to protect them from poison gas.

This development led to the production of granular carbon on a large scale. Today, the uses of activated carbon continue to grow. The material is used in a variety of industries, including corn and cane sugar refining , gas adsorption , dry cleaning , pharmaceuticals , fat and oil removal , alcoholic beverage production and much more. The biggest market for activated carbon is in the purification of municipal water supplies.

Water flotation is a common technique used to consolidate or separate charcoal from sediment matrix. There is little chance of actual contamination unless the water used for the flotation has petrochemicals in it or some highly organic suspension. The sample has a lot of surface area, and the alkali extractions used to remove humic acids many times cause the material to dissolve so that there is very little to date.
