Kemampuan Adsorpsi Arang Tandan Kosong Kelapa Sawit (Elaeis Guineensis Jacq.) Teraktivasi Hcl Sebagai Adsorben Escherichia Coli Dalam Larutan

Oil palm empty fruit bunches (Elaeis guineensis Jacq.) are one of the production residues in the form of solid waste that has the potential as activated charcoal as an Escherichia coli (E. coli) adsorbent. The presence of cellulose in oil palm empty fruit bunches plays an important role as a carbon source in adsorbing E. coli. This study aims to determine the variation of adsorbent dosage and contact time variation of HCl-activated palm empty fruit bunch charcoal in adsorbing E. coli. Oil palm empty fruit bunch charcoal was obtained through carbonization process at 300˚C for 120 minutes, then the charcoal was crushed using a 50 < x < 100 mesh sieve. Batch adsorption method was used in this study with variation of adsorbent dosage (0.25; 0.50; 1.00; 1.50 and 2.00 g) and variation of contact time (60, 90, 120 and 150 minutes). Characterization of HCl-activated oil palm empty fruit bunch charcoal refers to SNI 06-3730-1995 on methylene blue adsorbability test. Surface area, pore radius and pore volume were analyzed using Surface Area Analyzer with BET method. The surface morphology of the adsorbent was analyzed using SEM instrument. Measurement of the number of E. coli cells was carried out based on the turbidimetric method which is expressed in Optical Density (OD) using a UV-Vis Spectophotometer. The results of the characterization of activated charcoal of oil palm empty fruit bunches obtained Methylene Blue absorption capacity of 2.8927 mg/g. Based on BET test, the surface area was 0.5080 m2/g, pore radius was 2.9469 nm and pore volume was 0.0020 cc/g. The results showed that the optimum adsorbent dose was 1.50 g adsorbent dose with an average number of adsorbed E. coli cells of 3.48 × 108 cells/mL in 60 minutes of contact or E. coli adsorption efficiency of 61.96% and the best contact time at 150 minutes with an average number of adsorbed E. coli cells of 5.26 × 108 cells/mL or E. coli adsorption efficiency of 62.81%.
