泡沫塑料分离技术是近十几年来才应用到分析化学中的一种新的分离技术.泡沫塑料具有表面积大,化学稳定性好,对水的湿润性和渗透性强,容易得到,便于处理,可以再生等特点.而且还可以采用各种方法负载上不同的萃取剂或其它有机试剂制成具有不同性质的泡沫塑料以进一步提高分析方法的灵敏度及选择性.因此,它是一种比较理想的分离、富集金属离子的物质.预期这种分离富集技术在分析化学中将 Foam separation technology is applied to analytical chemistry in the last ten years, a new separation technology. Foam has a large surface area, chemical stability, water wetting and permeability, easy to get, easy to handle, Can be regenerated and so on.Also can also be used in various ways to load different extractants or other organic reagents made of different properties of the foam plastic to further improve the sensitivity and selectivity of the analytical method.Therefore it is a more ideal Separation, enrichment of metal ions in the material.It is expected that this separation and enrichment technology in analytical chemistry
