Adsorption of Pb (II) Ions from Aqueous Solutions by Water Hyacinth (Eichhornia Crassipes): Equilibrium and Kinetic Studies

Anzeze, Davis Amboga; Onyari, John Mmari; Gichuki, John W; Shiundu, Paul M (2014)

The Eichhornia crassipes roots for the removal of Pb (II) ions from aqueous solutions has been investigated. The adsorption of Pb (II) ions was found to be affected by solution pH, contact time, adsorbent dosage, initial ...
Biosorption of Zn (II) ions from aqueous solutions by water hyacinth (Eichhornia crasippes): Equilibrium and Kinetic studies

Anzeze, Davis Amboga; Onyari, John Mmari; Shiundu, Paul M; Gichuki, John W (2014)

The biosorption characteristics of Zn (II) ions were investigated. Experimental parameters affecting the biosorption process such as pH, contact time, biomass dosage, initial metal ion concentration, and temperature were ...
