含铜电镀污泥的固废属性鉴别研究

Study on Solid Waste Characteristic Identification of Copper-containing Electroplating Sludge

含铜电镀污泥来源不明、成分复杂,口岸不断发生以"铜矿"名义进口含铜污泥的现象,造成巨大经济损失和环境风险。借助X射线荧光光谱和衍射光谱分析,辅以外观、化学分析等手段,确定样品所含物质种类及含量,推断样品可能产生过程,对其属性进行判定,为口岸部门监管提供资料。

Copper-containing electroplating sludge has complex composition. The copper-containing sludge is continuously imported to our country in the name of ＂copper ore＂ at some ports, which results in huge economic losses and environmental risks. In this paper, types and contents of components in samples were determined by X-ray fluorescence and diffraction spectrometry assisted by appearance, chemical analysis so as to presume the possible production course. The characteristics were lastly identified to offer scientific basis to sectoral supervision at ports.
