    The purpose of this study was to test the ability of activated carbon from oil palm fronds to adsorb mercury ions in Batang Kuantan River. Oil palm fronds were carbonized by furnace at a temperature of 500oC for 1 hour and activated using NaOH in a ratio of 1:0, 1:1, 1:2, 1:3 and 1:4 (w/w). Carbon from oil palm frond activated by NaOH 1:4 showed the best characterization results. The concentration of mercury ion in Batang Kuantan River in the upstream, middle and downstream parts were 0.635 μg/L, 1.410 μg/L and 1.937 μg/L, respectively. NaOH 1:4 activated oil palm fronds carbon was contacted with river water for 40 minutes, the mercury ion concentration measured in Batang Kuantan River water was 0.173 μg/L (upstream), 0.382 μg/L (middle) and 0.527 μg/L (downstream). The mercury ion adsorption efficiency at each uptake point was 72.76%, 72.81% and 72.94%. Based on the data obtained, the activated carbon from the oil palm fronds was potentially used as mercury ions adsorbent in the water of the Batang Kuantan River.
