摘　　要：将葵花籽壳经过H_(2)O_(2)水热改性后制成吸附剂,并从吸附时间、氟离子浓度、pH、吸附剂投加量、干扰离子影响五个方面研究了其水中氟离子的吸附特性。结果表明,吸附平衡时间为3 h、pH为5.65、投加量为2.5 g/L时的吸附效果最佳,共存阴离子对F^(-)的吸附都有抑制作用,影响效果为Cl^(-)<NO_(3)^(-)<SO_(4)^(2-)<HCO_(3)^(-)<H_(2)PO_(4)^(-)。The sunflower seed shell was hydrothermally modif ied by H_(2)O_(2) to prepare adsorbent.The adsorption characteristics of fluoride ions in water were studied from five aspects:adsorption time,fluoride ion concentration,pH,adsorbent dosage and interference ions.The results showed that when the adsorption equilibrium time was 3 h,pH was 5.65,and the dosage was 2.5 g/L,the adsorption effect was the best.The coexisting anions inhibited the adsorption of F^(-),and the effect was Cl^(-)<NO_(3)^(-)<SO_(4)^(2-)<HCO_(3)^(-)<H_(2)PO_(4)^(-).
