Removal of Pb(II) and Cd(II) by Biomass Derived from Broadleaf Cattail and Water Hyacinth

The potential of cattail (Typha latifolia) and water hyacinth (Eichhornia crassipes) biomass to remove Pb Cd ions from metal solutions was determined. removal efficiency decreased with the increase in initial concentration aqueous solution but increased doses. biosorption unaffected by pH 5.0 6.5. Metal contact time then reached equilibrium about 45 min. Higher qmax (the Langmuir model) KF Freundlich constant) suggest that both have a greater affinity for Pb(II) than Cd(II). better fitness adsorption kinetics pseudo-second-order model pseudo-first-order indicates has an inclination toward chemisorption. present study showed are promising biosorbents provide green, practical, cheap household filtering systems rural communities.
