    Adam, Nor Hana
    This study aims to analyze the potential of oil palm frond activated carbon embedded with iron oxide nanoparticles (OPFAC-Fe) in removing humic acids (HAs) from stabilized leachate by the parameter of COD, colour and UV254. The raw oil palm frond (OPF) is activated with phosphoric acid (ratio of 1:3, 400 °C), followed by oxidationand embedding of ferric ions (Fe3+). The high surface area of 719.29 m2/g and numerous active sites were obtained on the OPFAC-Fe surface. The batch study indicates that the adsorption capacities (qmax,exp) of COD, colour and UV254 increased to 321.00 mg/g, 592.78 mg/g and 0.76 mg/g in the application of OPFAC-Fe. Isotherm model found the HAsdistributed in monolayer with a maximum adsorption capacity of 666.67 mg/g and favourable RL of 0.33 (0
