Before being discharged into the water, waste from the personal care products (PCP) industry needs to be treated using the adsorption process. In this study, activated carbon is chosen as adsorbent because of its organophilic property, abundance, and continuous system. The experiment was carried out in batches using 3 variables of COD concentrations in PCP wastes in 250 ppm, 225 ppm, and 200 ppm with the adsorbent mass amount of 0.3 g/l, 0.35 g/l, and 0.4 g/l. In this experiment, the effects of initial COD concentration, adsorbent mass, pH, and temperature on the adsorption process, equilibrium models and mass transfer coefficients of adsorption will be analyzed. Equilibrium models of Distribution Coefficient, Freundlich, and Langmuir Model, were implemented in this experiment. From results of the study, the equilibrium system of PCP waste and activated carbon using Langmuir Equilibrium achieved a removal value of 69.03% at concentration of 200 ppm and the adsorbent mass of 0.4 g/l. To determine the mass transfer coefficient, an external adsorption model was used. The coefficient value of mass transfer coefficient (kc) with the trial method is 3.78x10-8 m/min. Using numerical method with MATLAB, the result is 7.6222x10-8 m/min, while using the analytical approach, the result is 7.413x10-8 m/min.
