改性活性炭除砷研究进展

砷一直以来是我国优先控制的污染物,随着现代化的高速发展,水中砷污染问题愈演愈烈。如何高效,环保的去除水中的砷是一个重要的研究方向。相比于传统方法投资费用高,二次污染严重等缺点,日前新兴起的对活性炭进行改性来除砷效果显著。对近些年处理水中砷的方法进行了简单综述,并进行了总结与展望。

Research progress of Arsenic Removal by Modified Activated Carbon

Arsenic is a kind of pollutant that is strictly controlled in China; with the rapid development of modern society, arsenic pollution in water is getting more and more serious. How to remove the arsenic in water efficiently and environment friendly is an important research direction. The traditional methods have some shortcomings, such as high investment costs, serious secondary pollution and so on. Compared with them, a new modified activated carbon method for removing arsenic is better. In this paper, removing methods of arsenic in water in recent years were reviewed.
