通过静态实验,研究了活性氧化铝对氟离子的吸附性能,分析了活性氧化铝、投加量、吸附时间、pH值和废水温度对除氟的影响.研究表明,活性氧化铝的投加量与其吸附总量开始时基本呈线性增加的关系,但当活性氧化铝的量增加到一定量时其吸附总量将基本不再增加.当pH在3～5时,其吸附量最好,当温度增加时,其吸附总量在减少,振荡吸附时间为30 min时吸附基本达到平衡.%Through static experiment research on active aluminum oxide, fluoride ion on adsorption per-formance of activated alumina, dosage, adsorption time, pH value and temperature effects on the properties of waste water. Studies show that activated alumina dosage and adsorption amount at the start of the basic linear increase relation, but when activated alumina quantity increases to a certain amount of its adsorption amount will no longer increase. The amount of absorption of the best when the pH is in 3～5, when the water temperature increases the adsorption amount in reducing, oscillating adsorption time for 30 min when adsorption balance.
