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 Freu...

The conventional waste management practices dispose or incinerate agricultural and forestry waste, contributing to the environmental pollution while misusing biomass, a valuable resource with great potential of reuse. In fact, cultivation crops harvesting generate an abundant amount (e.g., stones, shells, straw) that can be used for wastewater treatment. Waste biomass may as: (i) adsorbent in i...
