The ever-increasing complexity of industrial products’ recycling calls for more efficient purification processes such as liquid/liquid extraction. Because of the high complexity of liquid/liquid extraction, optimizing a large-scale extraction is both time and resource consuming and can only be justified to solve high volume and value purification problems. It is therefore difficult to apply to small scale and highly variable waste material influx. We believe that using a fully automated and integrated microfluidic approach will enable fast and cost-effective studies of liquid/liquid extraction processes. This review presents an overview of liquid/liquid metal extraction performed using microfluidics platforms. We first give an overview of the extraction methods. We then review the most relevant characterization methods that have been integrated with such platforms.

工业产品循环利用的日益复杂性要求更有效的纯化工艺，例如液/液萃取。由于液/液提取的高度复杂性，优化大规模提取既耗时又耗费资源，并且仅能解决大量和有价值的纯化问题。因此，难以应用于小规模且高度可变的废料涌入。我们相信，使用全自动和集成的微流体方法将能够对液/液萃取过程进行快速且经济高效的研究。这篇综述介绍了使用微流控平台进行的液态/液态金属提取的概述。我们首先概述提取方法。
