Abstract
Abstract:
The current study deals with the removal of Lead ions from its aqueous solution by using polyacrylic acid beads. The process variables have been studied where time of contact, pH of solution, temperature, initial concentration. The adsorption capacity reached a maximum value of 565 mg/gm. after 24 hours. The study proved the applicability of pseudo first order of Langmuir model comparing with Frundlich model using the same conditions. The adsorption isotherms correspond well with shape (S) and by Giles isotherms. The thermodynamic study showed that the adsorption is endothermic process from positive value of ΔHo , while the positive value of entropy refers to the increased regularity of adsorption.
