Activated carbon binds to most substances through van der waals or london dispersion forces. how did you use ethanol to confirm that the pollutant had been removed from the water by adhering to the activated carbon?

The answer is a reaction of aqueous or absolute ethanol with the pollutant

Explanation:

Activated carbon filtration is a commonly used water treatment technology based on the adsorption of contaminants onto the surface of a filter. This method is effective for the removal of certain organics (such as unwanted taste and odours, micro-pollutants and synthetic organic chemicals), chlorine, fluorine or radon from drinking water or wastewater.

Carbonaceous resin have been known to be cleansed by ethanol 20% more effectively than steam.

Becauseof the hydrogen and van der waals force in a mixture of ethanol and water, releasing the pollutants into aqueous or absolute ethanol, and testing the resulting purity of the alcohol would determine whether or not purification of the water sample has occurred.
