- W2977857289 abstract "Water hyacinth and water spinach were used as novel precursor materials for the production of powdered activated carbons. They were activated chemically with H 3 PO 4 , KOH, H 2 O 2 pyrolyzed at 450 0 C and characterized in terms of pH, density, surface area, iodine number, porosity, ash content and moisture content. The surface area (m 2 /g) for the activated carbon samples; WSAP (1069), WHAP (1061), WSAA (1074), WHAA (1060) and WSBA (1009) were high and lied within the range of commercial grades (800-1500). The statistical t-Test analysis was used to determine if there was any significant difference between the surface characteristics of the activated carbons from the water weeds and commercial activated carbon (CAC) using a formulated null hypothesis at 95% confidence level. The study shows that there is no significant difference between the mean values of pH, porosity and density with those of CAC.
