Kesetimbangan Adsorpsi Methylene Bluepada Biochar Pelepah Kelapa Sawit Yang Disintesis Pada Suhu Pirolisis Bervariasi

Palm frond biomass derived from oil palm plantation waste has been developed as biochar because of its abundant availability and high cellulose and hemicellulose content. This study aims to obtain biochar with optimum pyrolysis temperature that can adsorb methylene blue dye. Palm frond biochar (BPS) was synthesized from palm frond biomass by pyrolysis at temperature variations of 500, 600 and 700 ℃ in N2 gas flow for 60 minutes to obtain BPS500, BPS600 and BPS700 and at the same time palm fronds were also carbonized in a clin drum for 60 minutes to obtain palm frond charcoal (APS). APS and BPS were characterized including moisture content, ash content, volatile substance content, fixed carbon by gavimetric method. The results of APS and BPS characterization showed that moisture content, ash content, and volatile substance content increased with higher pyrolysis temperature, while fixed carbon decreased. Morphological analysis and elemental composition were characterized by SEM-EDS. The results for SEM analysis showed that the pores produced by BPS were more fully formed when compared to the pore results in APS. The results of EDS analysis showed that as the pyrolysis temperature increased, the carbon element decreased. The adsorption capacity of methylene blue to APS and BPS was obtained at an optimum concentration of 50 ppm adsorbent dose of 0.05 g and contact time of 25 minutes with the optimum sample, BPS500, producing an average adsorption capacity of 24.5504 mg g-1 and an average adsorption efficiency of 99.05%. The maximum surface area was found in BPS500 sample of 389.50 m2 g-1. The suitable adsorption isotherm model based on the regression value (R2) close to 1 on APS, BPS500, BPS600 and BPS700 samples is the Langmuir adsorption isotherm model. Determination of surface area based on Langmuir isotherm showed a decrease as the pyrolysis temperature increased.
