攀枝花金沙江内镉离子的检验、提取与回收

Extraction and Recovery of Heavy Metal Cadmium in Jinsha River in Panzhihua

在我国工业发展的过程中,由于技术与管理的不到位造成了部分河流的污染。四川省攀枝花市作为一个工业城市,在发展过程中对本市人民赖以生存的河流——金沙江造成了污染。本文为了解金沙江内镉重金属污染情况,综述了几种检验方法,如:电感耦合等离子体质谱(ICP-MS)法、荧光分析法等。在此基础上查找了几种提取和回收重金属镉的方法,如:化学沉淀法、离子交换法等。在本文最后提出了检验、提取、利用重金属镉的适宜方案。

In the process of the industrial productioin in China,the pollution in some rivers was caused by the lack of technology and managemen as well. Jinsha River in Panzhihua in Sichuan province had been polluted during the development of the city. The cases of the heavy metal cadmium pollution in the Jinsha River,how to deal with this water pollution,and the methods included inductively coupled plasma mass spectrometry（ ICP-MS）,fluorescence analysis,etc. were reviewed. Based on these,several methods for the extraction and recovery of the heavy metal cadmium,including the chemical precipitation,ion exchange,and so on,were discussed. An optimum scheme for the inspection,extraction and utilization of heavy metal cadmium was put forward.
