The effect of contact time, temperature, pH solution and biosorbent dosage has been studied. ChiPandan gave optimal adsorption performance when operated at 0.1g of adsorbent with pH of 6 at ambient temperature for 60 minutes of contact time. Whereas, raw Pandan was found to give a better performance at 2.0g of adsorbent, pH of 5, 60°C and 90 minutes of contact time. Raw Chitosan needed 1.0g of adsorbent, pH 5, 70°C with 120 minutes of reaction time for a maximum Chromium(VI) ions removal performance. From these result, it can concluded that ChiPandan could be a good adsorbent for the Chromium(VI) ions removal from aqueous solution.
