从不同废弃物中回收贵金属钯的湿法回收方法,明确了钯回收的重要价值,但存在体系成分复杂,含量极低,且未经处理直接排放,造成资源浪费的问题。湿法回收依据回收过程作用机理的不同,以吸附法、离子交换法、络合-萃取法、沉淀法等进行分类阐述。在4种方法中,吸附法的应用逐渐增加,故以吸附法为主进行详细介绍。吸附材料可分为金属氧化物复合吸附材料、碳基复合吸附材料、MOFs复合吸附材料、生物质复合吸附材料。而复合吸附材料通常以功能性配体与载体通过嫁接法或浸渍法等进行复配合成,因而相对普通的吸附剂具有更高的吸附容量与选择性,且吸附迅速。指出在未来的发展方向中,为推进贵金属钯回收的高...

The wet recovery methods for recovering precious metal palladium from different wastes were reviewed, and the important value of palladium recovery was clear, but there are problems of complex system components, extremely low content and direct discharge without treatment resulting in waste of resources. According to the different recovery mechanism of wet process, the wet recovery methods were classified and described by adsorption method, ion exchange method, complexation-extraction method, precipitation method and so on. Among the four metho...
