Successfully made activated carbon from mangosteen peel, which was physically activated and then chemically activated by ZnCl2 (ACMP), with a mass ratio of MP: ZnCl2 equal to 2:1, activation temperature 500 0C, time. Activate for 180 minutes. Fabricated ACMP activated carbon has graphite structure, porous surface, specific surface area is 419,8554 m²/g, iodine index is 825 mg/g
isoelectric point is equal to 5.34. The CIP adsorption efficiency was 98% at the initial concentration of 50 ppm. The maximum adsorption capacity CIP for ACMP has been determined as qmax = 29.78 mg/g.
