The urgency of the thesis The pollution of ammonia arsenic and heavy metal in supplied and drinking water in Vietnam was not strictly treated yet even deferent solutions were applied such as biological treatment aeration at high pH oxidation by chlorine adsorption Adsorption methods using materials such as zeolite silica polymers or activated carbon were recognized as a simple application technics to remove pollution substances. Activated carbon is material having more advantages than others such as low cost available easy to use stable in acidic and basic environment high mechanic stability and regeneration possibility. Activated carbon has relatively hydrophobic surface therefore it can be very good used for treatment of non polar or less polar organic substances 2 but it is less effective in treatment of compounds in ionic forms 3 4 . Activated carbon as its nature has reductive groups in its surface so it can be oxidized to transform to different functional groups such as carboxylic acids and other weak or very weak acids. For that
