The main objective of this study was to investigate the use of water hyacinth ash in Sorption of heavy metals from wastewater. This was through determining; the characteristics of the water hyacinth plants obtained from Port Bell Luzira, the physiochemical characteristics of wastewater obtained from Nakivubo Channel and the Sorption efficiency of water hyacinth ash as biosorbent in the Sorption of Iron, Copper and Cadmium ions from wastewater. From the results, it was concluded that the WHA has a high number of binding on to which the metal ion could get biosorbed and there is a possibility of using water hyacinth as an effective and low-cost method for Sorption of heavy metals from the wastewater.
