| 摘 要： | 通过静态试验，研究了活性氧化铝对F-的吸附性能，分析了原水氟离子浓度、pH值、活性氧化铝的投加量和吸附时间对吸附性能的影响。研究结果表明：在原水浓度0～50mg／L范围内，活性氧化铝吸附量与原水浓度基本成线性增加的关系；活性氧化铝除氟的最佳pH值为5～7，最佳投加量为10g／L。测定了在25℃时活性氧化铝除氟的吸附等温线，并对吸附等温线进行拟合，证明其符合Langmuir吸附等温式。

| Abstract: | The adsorption properties of activated aluminum oxide to F - ion were researched by captive test in the paper. The effects of the initial fluorine concentration, pH, the dosage of activated aluminum oxide and adsorption time on the adsorption properties were studied, The results showed that the adsorption capacity of activated aluminum oxide linearly increase within the initial fluorine concentration rang from 0 -50 mg/L, the optimal pH value was from 5 to 7 ,the optimal dosage was 10g/L. The adsorption isotherm of activated aluminum oxide at 25℃ was made and it obeys Langmuir Equation that has already be proved. |
