氨荒酸膦酸树脂滤器的制备及其在AAS分析中的应用研究

Preparation of phosphonicdithiocarbamate resins filter and their applications in AAS and AFS

介绍了氨荒酸膦酸树脂过滤器的制备方法,以及应用该过滤器分离与富集地面水(海水)中Cu、Pb、Zn、Cd等元素的适用条件。实际样品中的Cu、Pb、Zn、Cd等重金属离子经过过滤器过滤,被吸附在树脂滤层中,用少量酸洗脱,以AAS测试,结果稳定、准确度高。此过滤器在痕量分析中具有很高的应用价值。

A method has been presented for the preparation of phosphonicdithiocarbamate resins filter The applicable condition has been defined for filtering and concentrating Cu, Pb, Zn, Cd, Hg, As in surface water and seawater by the filter A real filtered and concentrated water sample has been tested by AAS or AFS, it's result is stable and accurateThis kind of filter is of highly use value in trace analysis
