| Abstract: | The adsorption of reaction kinetics and adsorption of thermodynamics of peat for the adsorption of Pb2+ from aqueous has been investigated.The dosage of peat,initial Pb2+ iron concentration,initial solution pH and temperature impact of adsorption are inspected.The results show that peat has a better adsorption capability;the rate of Pb2+ adsorption on peat was compatible with Lagergren pseudo-second order kinetics parameters;the adsorption thermodynamics of Pb2+ was fitted to Langmuir parameters and Freundl... |
