This study introduces the results of the research on the construction of the process of making adsorbent materials from coffee husk and evaluates the applicability to treat Cr(VI) in water. The adsorbent material is made through 2 stages: Pyrolysis at 350 oC, 1 h and impregnation with KOH 1 M, 24 h, pyrolysis 700 oC, 2 h. Materials were evaluated for their properties and factors that affect the adsorption process. The results showed that the treatment efficiency of Cr(VI) in water reached 98,72% at pH 3, 180 minutes and the adsorption material ratio was 0,5 g/100 mL. The pseudo-sencond-order kinetic model and the Langmuir isothermal adsorption model were suitable for describing the adsorption process of materials with Cr(VI).
