Comparative Study of Three Differently Produced Activated Carbons from Borassusaethiopum

Abstract

This study was initiated with the aim of helping rural populations in the production of an activated carbon capable of depolluting water on an ad hoc basis. Borassusaethiopumcarbon, with a carbon content of 71%, was selected in contrast to manioc can charcoal, which has a carbon content of 56%. After producing activated carbon using three methods (i.e. carbon impregnation and hot washing, steam activation and impregnation followed by kiln drying at 450 °C(CAF)), the chemical activation method with kiln intervention proved to be the most effective. This choice was based on COD removal rates. COD removal rates of 57.61, 87.46, 51.04 and 74.32 were obtained by considering experiments 1, 2, 3 and 4. Turbidity was also reduced to the WHO standard using CAF.
