Abstract
Shell of ketapang (Terminalia catappa) has chemical composition of cellulose and lignin as a carbon source, which potentially to be used as an adsorbent in the adsorption process. This study aimed to change ketapang shells into charcoal by carbonization at temperature of 500oC with various times (15 and 30 minutes). Charcoal of ketapang shells were applied to the peat water treatment by measuring parameters of organic matter and Fe content. In this experiment, organic matter and Fe content in the peat water were determined by permanganometry and Atomic Absorption Spectrophotometry (AAS) methods. The initial condition of organic matter and Fe content in the peat water were 312.6504 mgL-1 and 6.7272 mgL-1. Adsorption treatment of organic matter and Fe content by charcoal of ketapang shells were observed with various mass (2 and 4 grams). The results of experiment showed with the mass of adsorbent 4 grams could reduce 25.21% of organic matter content by charcoal carbonization resulted for 15 minutes and 15.55% Fe content by charcoal carbonization resulted for 30 minutes. Peat water treatment by using charcoal of ketapang shells can not be able to reduce organic matter and Fe content according to the standard limits for drinking water.
