共沉淀分离和富集方法,是分析化学中常用的分析方法,由于不需特殊的试剂和设备,至今在环境监测、纯物质的分析、化学光谱分析、X-萤光分析、稀有和稀散元素的分离和富集等方面,仍不失为简易、有效的方法之一。但在文献中尚未见对采用共沉淀分离和富集的离子和 Coprecipitation separation and enrichment methods, analytical chemistry is commonly used in analytical methods, as no special reagents and equipment, so far in environmental monitoring, pure substance analysis, chemical spectrum analysis, X-fluorescence analysis, rare and scattered elements The separation and enrichment, etc., is still a simple and effective method. However, there is no literature on the use of co-precipitation separation and enrichment of ions and
