Impregnasi Fe Pada Arang Cangkang Buah Ketapang (Terminalia Catappa) Dan Apli…

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-Fe by carbonization and impregnation process. Carbonization carried out at temperature of 500oC with variation times 15 and 30 minutes, was impregnated precurso…
