Abstract :
A novel adsorbent-activated ferric hydroxide adsorbent (AFe) was synthesized by reaction of FeCl3 with NaOH with additive of PVA. Adsorption experiments of fluoride at different concentrations and pH were carried out on AFe and activated alumina (AA). The results showed that AFe performed very well for F adsorption, Its adsorption capacity was 10 times of that of AA at 5 mg/L equilibrium level. The AFe also showed wider adaptive range to pH change and disturbing ions. The result shows the potential application of the adsorbent for effective F removal from drink water.
