Penyisihan Logam Cd (Ii) Dan Cr (Vi) Menggunakan Adsorben Hollow Carbon Fiber Daun Akasia (Acacia Mangium Willd)

---

Disposal of waste containing heavy metals such as cadmium Cd (II) and chromium Cr (VI) in high concentrations into water bodies can pollute the environment and interfere with human health. One method that can be used to reduce heavy metal levels is the adsorption method using adsorbents as absorbent materials. Hollow carbon fibre acacia is one of the adsorbents that can be used as an adsorbent because it has large surface area characteristics. This study aims to determine the removal efficiency and adsorption capacity of hollow carbon fibre acacia on Cd (II) and Cr (VI) metals and to study the kinetics and isotherms of adsorption. This study used adsorbent dose variation (2, 3, and 4) g/L, contact time variation (5, 10, 15, 30, 60, 90, 120, and 180) minutes, and initial concentration variation (5, 10, 15, 20, 25, 30, and 35) mg/L. BET analysis characterisation results obtained surface area of hollow carbon fibre acacia of 291.507 m2/g. Optimum conditions were obtained at a dose of 4 g/L and a contact time of 120 minutes with removal efficiency and adsorption capacity on Cd (II) metal of 99.4% and 3.18 mg/g, and 99.5% and 2.61 mg/g on Cr (VI) metal. The suitable kinetics and isotherm models for adsorption of Cd(II) and Cr(VI) metals using acacia hollow carbon fibre adsorbent are pseudo second order kinetics and Frenudlich isotherm.
