Carbon Black has various advantageous properties such as reinforcement, tinting, weathering, chemical resistance, electrical resistance, etc., but it has poor affinity in the solution. The purpose of this study is to enhance dispersion in the aqueous solution by altering the surface characteristics. Two different treatments were applied for both channel black and furnace black respectively. Channel black was treated in alkaline solution to replace hydrogen of the carboxyl group with alkaline metal, Li, Na, K. Furnace black has few functional groups, and it was treated with $HNO_3$ to increase the number of functional group on carbon black. It was seen that the substitution of alkaline metal on the surface of channel black enhances the degree of dispersion. Also the higher the acid concentration and reaction temperature, the more the number of some functional groups on the furnace black. Reaction time was not seen to be effective.
