| 摘 要： | 对粉末状骨炭的除氟性能进行了多组试验研究,结果表明:粉末状骨炭的吸附容量与原水中氟离子的浓度呈线性关系,吸附等温式符合Freundlich公式。骨炭吸附容量受骨炭粒径、pH值、水温及水中其他离子的影响,骨炭粒径还会影响吸附反应的速度。骨炭采用5%的NaOH溶液再生,再生效果良好。

| Abstract: | The removal efficiency of fluorine by powder bone black was studied by several experiments. It is concluded that the adsorption capacity of powder bone black is linear with the concentration of fluorine in raw water, and the adsorption isothermal formula accords with the Freundlich formula. The adsorption capacity of powder bone black is affected by the particle size of bone black, pH, water temperature and other ions, and the particle size of bone black can also affect the adsorption speed. The bone black would be regenerated by NaOH solution of 5% with high efficiency. |
