【摘要】 本文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多元素的适用条件。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。更多还原

【Abstract】 This paper introduced the preparation method on filter of phosphoric acid resin, and the conditions of application to separate Cu, Pb, Zn, Cd from the ground water and ocean water. Heavy metal, such as Cu, Pb, Zn, Cd, through the filter, are absorbed in resion, with a little acid to wash. The result is steady and accurate in AAS test. The filter have very high application value in trace analysis.更多还原
