The adsorption of reaction kinetics and adsorption of thermodynamics of peat for the adsorption of Pb^2+ from aqueous has been investigated. The dosage of peat, initial Pb^2+ 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 Pb^2+ adsorption on peat was compatible with Lagergren pseudo-second order kinetics parameters; the adsorption thermodynamics of Pb^2+ was fitted to Langmuir parameters and Freundlich parameters, furthermore the adso...
