Abstract—An Atomic Absorption Spectroscopy has been used to analyze absorption of Fe⁺³ ions by activated carbon made of Paraserianthes Falcaria wood. This was done to make use of this easily grown plant as material for producing carbon suitable for heavy metal filtration system. Carbon made of Paraserianthes Falcaria wood was grinded and sieved to 100mesh. This carbon was chemically and physically activated before being used to absorb Fe⁺³ ions in simulated waste water. The concentration of Fe⁺³ ions in the simulated waste water and the activated carbon mass were varied. The results show that the absorption efficiency increases with the increase of activated carbon mass. On the other hand the absorption efficiency deceases with the increase of Fe⁺³ ions concentration in simulated waste water.

Index Terms—Paraserianthes Falcaria, activated carbon, Fe+3 ion, atomic absorption spectroscopy.
