摘　　要：文章旨在研究改性骨炭对饮用水中氟离子的去除效果。用AlCl3对常见的骨炭进行改性,并考察了pH、氟溶液初始浓度、温度及吸附剂用量对氟离子吸附去除的影响。结果表明:经AlCl3溶液改性的骨炭,用量为0.2 g/L时,其在24 h内对10 mg/L氟离子的去除率达97%以上。该吸附剂比未改性效果好,具有一定的应用前景。The aim was to study the removal of fluoride from drinking water by modified bone charcoal.The common bone charcoal was modified by AlCl3,and effects of some factors like pH,fluoride concentration,temperature and adsorbent amount on the removal of fluorideion were studied.The result showed that when the amount of bone charcoal modified by AlCl3 solution was 0.2 g/L,the removal rate of 10 mg/L fluoride reached more than 97 % with in 24 h.It was concluded that the effect of adsorbent is better than unmodified,and the adsorbent had a certain application prospect.
