Abstract

Conducting polypyrrole(PPy) was found to possess potential efficiency to remove F from aqueous solutions. In this study doped with Cl PPyCl/ATP composites were prepared via in-situ polymerization and employed as adsorbent to remove from aqueous solutions. The ability of the adsorbent to remove F from aqueous solution was demonstrated in a batch sorption mode. External factors such as initial concentration of F , contact time, adsorbent dosage and pH value of solution how to influence the adsorption efficiency of composites were investigated. The results showed that the adsorption efficiency is strongly pH, initial concentration and adsorbent dose dependent. Experiment data fitted well to the Langmuir isotherm model. The adsorption kinetics is described by the pseudo-second-order model. Meanwhile, the adsorption may proceed by an ion exchange mechanism between Cl and F .
