由于重金属在环境中不能被降解，只能发生迁移和转化，重金属污染对环境构成严重威胁，引起人们特别关注。目前，处理重金属废水的方法有吸附法、化学沉淀法、离子交换法、生物吸附法、电化学法、电解法、膜分离法等。吸附方法在重金属废水处理领域有着一定的优势。吸附法关键是要获得高性能、低成本的吸附剂。对吸附剂在处理重金属废水的最新进展进行了阐述，对其发展趋势及前景做了展望。
由于重金屬在環境中不能被降解，隻能髮生遷移和轉化，重金屬汙染對環境構成嚴重威脅，引起人們特彆關註。目前，處理重金屬廢水的方法有吸附法、化學沉澱法、離子交換法、生物吸附法、電化學法、電解法、膜分離法等。吸附方法在重金屬廢水處理領域有著一定的優勢。吸附法關鍵是要穫得高性能、低成本的吸附劑。對吸附劑在處理重金屬廢水的最新進展進行瞭闡述，對其髮展趨勢及前景做瞭展望。

Pollution of heavy metals has attracted much attention ,because heavy metals could not be degraded and could only be transported and converted. At present,the methods for treating heavy metals are adsorption,chemical precipitation,ion exchange,bio-sorption,electrochemistry,electrolysis,membrane separation,and so on. Adsorption technology has certain superiority in the field of heavy metal wastewater treatment. The key of adsorption technology is to obtain adsorbents with high capability and low cost. The newest progress in the adsorbents for treating heavy metal wastewater is expounded,and its development trends and prospect are forecast.
