从工业废物中回收金属镍的研究进展

Research Advances on Nickel Recovery from Industrial Wastes

金属镍具有优良的抗腐蚀性能在工业生产中被广泛应用。因此含镍废物如废电池、废催化剂、含镍电解质废水等势必大量产生。若这些含镍废物得不到很好处理,将会对土壤、水,空气以及人体健康造成严重的影响。本文分析从废水、废电池、废催化剂、电子废物以及其它含镍废物中回收镍的技术与方法。

Metal nickel was heavily utilized in industry due to its anticorrosion properties. As a consequence, nickel containing wastes such as spent batteries and catalysts, wastewater and bleed - off electrolytes were generated. If these wastes were not treated well, they would result in environmental pollution and impact on human health. The recovery methods and technology from spent batteries and catalysts, wastewater and other sources containing nickel were reviewed.
