KARBONISASI LIMBAH PELEPAH KELAPA SAWIT SEBAGAI ADSORBEN UNTUK MENGURANGI KADAR Fe (III) PADA AIR GAMBUT

Abstract

Oil palm fronds are waste generated from oil palm plantations from pre to post harvest. These palm fronds have not been used optimally, they are usually burned or used as fertilizer. Palm fronds contain high cellulose and make the oil palm fronds potentialy as adsorbent. Shynthesis of COPF (Charcoal oil palm fronds) use carbonization method. COPF shynthesis process begin with collecting the palm fronds waste, then drying under sunlight continuous in oven for 2 hours. Next step homogenity size particle by sieving with unit 80 mesh and 120 mesh followed by carbonization, carbonization temperature 600 0C for 60 minutes. Moisture and ash content were determined with gravimetry, also applied in adsorption Fe (III) in peat water with contact time, mass adsorben and volume of peat water variations. Moisture value of adsorbent is 2,392% and the ash content 9,958%. Both of them qualify the technical activated charcoal requirements according SNI 06-3730-1995. The best result of adsorption Fe (III) in peat water show in contact time was 30 minutes, mass adsorben was 1 g and volume of peat water was 100 mL. The higher adsorption efficiency is 96,13% and capacity 0,052 mgg- 1. COPF is effectively used in reducing Fe (III) levels in peat water as evidence by its high adsorption effciency.
