活性炭纤维电吸附法去除饮用水氟离子方法探究
|
摘要
氟是人体必需的元素,对人体有着重要的生理功能。如果人摄入的氟过量,人体将受到较大危害。除氟的方法有很多,电吸附方法是将传统的吸附技术与电化学方法融合,使得电吸附方法与传统的去离子方法相比具有相当的优势:无二次污染,能量利用率高,操作简单,是具有研究和开发价值的清洁型技术。用活性炭纤维做吸附剂对蒸馏水配制成的含氟水去除率显著,为了达到氟离子去除效果,要调节温度、电极电势以及原液浓度,注意电极与吸附材料的选择。
Fluorine is an essential element of the human body which has an important physiological function. If people intake excessive fluoride,the body will receive more damage. Electrosorption is a method that integrates electrochemical adsorption and traditional adsorption. It is more advantage than the other methods,such as no additional waste,high capacitance energy utilization,operated simple. It is a research and development value of clean technologies. Using carbon material in electric adsorption of removing fluoride in drinking water can obtain significant reduction. The three parameters,the temperature,electrode potential and the liquid concentration should be adjusted to get better results.
