Studi Adsorpsi Air Gambut Menggunakan Magnetic Biochar Berbahan Dasar Pelepah Kelapa Sawit

---

ABSTRACT
Peat water has a brownish red color because it contains high organic matter. Adsorption using magnetic biochar as an adsorbent is one of the peat water treatment methods. Magnetic biochar is the result of magnetization of biochar by adding chemicals containing metal ions, and pyrolysis with little or no oxygen. Palm fronds have the potential to be used as a base material for magnetic biochar because they contain cellulose, hemicellulose, and lignin. This study aims to analyze the effect of contact time, pH, adsorbent dose, and initial concentration on the adsorption of color and organic matter in peat water and determine the reaction kinetics and adsorption isotherms. This study used variations in contact time 5, 15, 30, 60, 90, 120, 180 minutes, pH 2, 3, 4, 5, 6, adsorbent doses 6.8; 8.55 ; 10.3 g/L, initial concentrations 20%, 30%, 40%, 50%, 60%, 70%, 80% and 100% peat water. The results of this study showed that the highest removal of color and organic matter was found at contact time of 90 minutes, pH 2, adsorbent dose of 10.3 g/L, initial concentration of color 100 PtCo and organic matter of 20.22 mg/L with efficiency of removal of color and organic matter of 92% and 93.15% and the adsorption capacity of organic matter was 1.87 mg/g. The appropriate kinetic models are pseudo second order with an R2 value of 0.9973 and the Freundlich isotherm model with an R2 value of 0.9153.
