Activated carbon is a cheap carbon material with high specific surface area, porosity, and electrical conductivity. This fact makes the various applications of activated carbon as an adsorbent, water treatment, and energy sector. Activated carbon dispersion studies facilitate the application of activated carbon as a primary material in the design of electrodes in fuel cells and batteries. In this study, dispersion studies of activated carbon were carried out in an aqueous system using surface active agents (surfactants) Cetyl Trimethyl Ammonium Bromide (CTAB), Sodium Dodecyl Sulfate (SDS), and Polysorbate 80 (Tween 80). The ratio of activated carbon to surfactants varies from 1:0–1:5 for each surfactant. The UV-Vis spectrophotometer measurements at a wavelength of 200–500 nm showed that Tween 80 surfactant with a 0,05 g activated carbon with 3 mL Tween 80 could disperse activated carbon in water solvents better than CTAB and SDS.
