浮选法由于简便和可靠而广泛用于痕量分析,它主要用于预富集天然水和高纯金属中低ppm级或ppb级的痕量元素,但也可用于分离天然水和废水中的其它物质。目前,浮选法的应用可分为两类:沉淀浮选法和离子浮选法。本文讨论了痕量分析中浮选法的一般原理、技术和应用。
Flotation is widely used for trace analysis because of its simplicity and reliability. It is mainly used for the pre-enrichment of low-ppm or ppb trace elements in natural and high-purity metals but can also be used to separate natural and wastewater Other substances. At present, the application of flotation method can be divided into two categories: precipitation flotation and ionic flotation. This article discusses the general principles, techniques and applications of flotation in trace analysis.
