Pemanfaatan Potensi Tandan Kosong Kelapa Sawit Sebagai Karbon Aktif Untuk Pembersih Air Limbah Aktivitas Penambangan Emas Di Taluk Kuantan

The usage of biomass as activated carbon for waste water cleaning aplicationcan be fabricated with a combine of the activation and carbonization methods. Activated carbon was made from oil palm empty fruit bunches (EFB) by the processing stage cobs into carbon pellets form, then the carbonization was processing at temperature of 800 0C for 7 hours 50 minutes in thepressure of nitrogen (N2). Concentration of KOH was 0.3 M as chemical activation solutation. Scanning Electron Microscopies (SEM) methode and X-Ray Diffraction (XRD) was used to analyze the structure and surface morphology and crystalineproperties of activated carbon of pellets EFB. While the composition of chemical elements onto the sample was analyzed by using Energy Dispersive X-ray (EDX). Activated carbon adsorption for heavy metals was measuredby using Atomic Absorption Spectrophotometer (AAS) with a wavelength of 248.3 nm (Fe) and 213.9 nm (Zn). XRD analysis results showed that the carbon peak appearing at 2θ 24.830o (002) and 44.534o (100). Fe appeared at 2θ 32.824 (020), 44.648 (021), 64.896 (131), and 82.294 (212). Zn appeared at 2θ 29.379 (-312) and 44.658 (-115). EDX spectrum indicate the presence of the elements carbon (C) 79.79%, the maximum contamination of Fe 2.36% and 0.61% Zn. And the adsorpsion of heavy metal was measured by SSA that showedthe optimum adsorption of 78.52% Fe at the contact time for 5 hours and Zn 77.23% with optimum contact time for 3 hours. The results showed that the active carbon pellet EFB have a high adsorption of the heavy metals of iron (Fe).
