摘要：Adsorption is considered as the most promising treatment technology for fluoride (F) removal from aqueous solutions. The aim of this study was to determine the efficiency of seed Moringa oleifera ash in removal of F from aqueous solutions. After determining optimum pH (pH=7) and ashing temperature (650º C) by pretests, the adsorption experiments were studied in batch systems at room temperature. The effects of experimental parameters such as adsorbent dose (0.8 – 64 g/l), contact time (5 -120 min) and initial F concentration (2 -8 mg/l) were studied. The highest removal adsorption was at 64 g/l adsorbent, 10 min contact time and initial F concentration at 8 mg/l (81.14 % F removal). The results showed that the Moringa Oleifera ash can be used as an environmental friendly, cheap and effective adsorbent from aqueous solutions.
