Kinetics and thermodynamic investigation of phosphate adsorption on AlCl3 modified palygorskite

摘要：

　　The potential of AlCl3 modified palygorskite was assessed for adsorption of phosphate from aqueous solutions.The Langmuir isotherm adequately described adsorption with an R2 goodness of fit of 0.9683.The process kinetics was found to follow the pseudo-second-order model.Positive Δ-H and ΔS values indicated that the adsorption of phosphate onto AlCl3 modified palygorskite was endothermic.Negative ΔG showed that the adsorption of phosphate onto this sorbent is feasible and spontaneous.
