Efisiensi Adsorpsi Arang Aktif Dari Cangkang Kelapa Sawit (Elaeis Guineensis Jacq.) Sebagai Adsorben Escherichia Coli Dengan Metode Batch

---

Palm shell charcoal (Elaeis guineensis Jacq.) has the potential to be used as an adsorbent to adsorb Escherichia coli (E. coli), however its adsorption efficiency is relatively small. Therefore, to increase its adsorption efficiency in this study palm shell charcoal will be activated with ZnCl2 to adsorb E. coli with the batch method. The aim of this study was to analyze the concentration of ZnCl2 activator variation and particle size variation palm shell on the adsorb E. coli. Palm shell charcoal is made through a carbonization process at a temperature of 400oC for 2 hour, then crushed at size that passes 30 mesh and is retained in 50 mesh, that passes 50 mesh and is retained in 100 mesh, passes 100 mesh and is retained in 200 mesh. Charcoal were activated using zinc chloride (ZnCl2) with the concentration of ZnCl2 activator variation 0.5 M, 1 M, 1.5 M, and 2 M. Characterization of palm shell activated carbon refers to SNI 06-3730-1995 by adsorption test for iodine and methylene blue. Surface area, pore volume, along pore radius was analyzed using a surface area analyzer using the BET method. Surface morphology using SEM instrument. The characterization results of activated carbon palm shell obtained an iodine adsorption capacity of 163.2696 mg/g and methylene blue adsorption capacity of 1.0021 mg/g. Based on the results of the BET obtained surface area of 16.1740 m2/g, a pore radius of 2.1763 nm, and a pore volume of 8.8 × 10-3 cc/g. The optimum adsorption conditions with the batch method were obtained at the optimum concentration of ZnCl2 activator of 1.5 M with an average amount of E. coli adsorbed of 5.13 × 108 cells/mL in 1 g of activated carbon or adsorption efficiency of E. coli of 81.95% and particle size of 50 mesh with an average amount of E. coli adsorbed of 8.86 × 108 cells/mL in 1 g of activated carbon or adsorption efficiency of E. coli of 81.81%.
