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.
1. Take 100ml of water as solvent and boil it few minutes. 2. Now add one tea spoon sugar, one tea spoon tea leaves and 50ml of milk. Here sugar, tea leaves and milk are solute. 3. Now boil it again for few minutes so that sugar will dissolves in solution as sugar is soluble in water 4. Now filter the solution. Collect the filtrate in cup. The insoluble tea leaves will be left behind as residue.
