Abstract :

The adsorption of heavy metals on water hyacinth powder from both wastewater and aqueous solution was studied using batch experiments. The adsorption efficiency of water hyacinth powder was evaluated in this study. The levels of heavy metals in wastewater were in the range of 1.2 75.3 ppm for lead, 0.4 87.6 ppm for chromium, 0.1 63.5 ppm for nickel, 0.5 95.5 ppm for zinc and 0.8 52.7 ppm for cadmium. The levels of zinc, lead and cadmium were above the limits set by the write NEMA in full then bracket NEMA for discharge into the environment 0.01 ppm for cadmium and lead, 0.5 ppm for zinc . The adsorption efficiency of hyacinth powder was higher in aqueous solution than in wastewater while at low metal concentrations 0.1 3.2 ppm , the adsorption efficiency of water hyacinth powder was 100 in both wastewater and aqueous solution. The study showed that water hyacinth powder is a low cost adsorbent which could be used to remove heavy metals from wastewater and aqueous solution. J. M. Mwaniki | J. O. Onyatta | A. O.
