水中氟离子吸附法综述研究

Research on a Summary of the Fluoride Ion Adsorption Method in Water

我国水体污染情况日益严重,其中饮用水中氟离子的污染情况尤为突出,人体摄入过量氟时,将会导致身体骨骼疾病。如今水体除氟方法主要包含絮凝沉淀法、离子交换法、膜处理法和吸附法等。其中吸附法由于成本低且效果好被广泛使用,因此本文针对饮用水中去除氟离子吸附方法,对常用吸附剂进行归类并对比分析,并对未来发展趋势提出进一步展望。

The pollution of water bodies in China is becoming more and more serious.The pollution of fluoride ions in drinking water is particularly prominent.Excessive f luoride in the human body will cause bone diseases.Nowadays,the defluorination methods of water mainly include flocculation precipitation method,ion exchange method,membrane treatment method and adsorption method.Among them,the adsorption method is widely used because of its low cost and good effect.Therefore,this paper classifies and comparatively analyzes the commonly used adsorbents for the method of removing fluoride ions from drinking water,and proposes further prospects for future development trends.
