摘要
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 accurateThis kind of filter is of highly use value in trace analysis
