Oil Palm Frond (OPF) based Activated Carbon in Leachate Treatment
Modified activated carbon (AC) was prepared from oil palm waste in leachate treatment. Batch adsorption study was employed to investigate the effect of adsorbent dosage and contact time in removing COD, colour and iron (Fe) from leachate. COD, colour and iron (Fe) were measured using USEPA Digestion Method, Platinum-Cobalt Standard Method and Atomic Analyzer Spectroscopy (AAS). The chemical and physical characterization of adsorbent was determined by Scanning Electron Spectroscopy (SEM), Elementary Diffraction X-Ray (EDX), Brunauer–Emmett–Teller (BET) and Fourier Transform Infrared (FTIR). Results obtained shows the presence of nanopores (412.1-994.6nm) and oxygen elements (16.76%) on AC’s surface. BET and micropore surface area were 1357.258m2/g and 384.621m2/g respectively, while pore volume was 0.191cm3/g. Hydroxyl functional groups was also observed from FTIR analysis. The highest recorded removal of COD, colour and iron (Fe) were 82.52%, 80.25% and 59.25%.
