摘　　要：羟基磷灰石(HAP)是一种新型的氟离子吸附剂。以模拟含氟水样为处理对象,采用静态吸附实验研究了温度、p H值、吸附时间等因素对HAP除氟性能的影响。探讨了HAP吸附剂的等温吸附过程。结果表明:HAP的最大吸附量为5.32mg/g;50min之内吸附速率较快,在60min时吸附过程趋于平衡;酸性环境下吸附效果较好;升高温度有利于吸附的进行且吸附过程符合Langmuir模型。该研究可为HAP工业应用提供可靠的理论基础和科学依据。The hydroxyapatite （HAP） is a new type of fluoride ion adsorbent. The effects of temperature, pH value, adsorption time and other factors on the fluoride removal efficiency are studied by static adsorption experiment with simulated fluorine-containing water as sample. The isothermal adsorption process of HAP adsorbent is investigated. The results show that the maximum adsorption capacity of fluoride ion with HAP is 5.32mg/g. The adsorption rate is rapid in the first 50min and it will take 60rain to approach the adsorption equilibrium. The efficiency of adsorption is obvious in acidic environment and higher temperature is conducive to the adsorption process. The isothermal adsorption process obeys the Langmuir adsorption model. This study will provide a reliable theoretical foundation and scientific basis for the industrial application of HAP.
