摘　　要：以负载了PAN的微晶萘为吸附剂 ,以乙醇为洗脱剂 ,富集天然水中的铜、钴和铬 ,再用原子吸收光谱法 (AAS)测定 .对富集条件进行了试验 ,方法回收率为 95 %～ 10 5 % .A new method for enrichment of trace amounts of copper,cobalt and chromium in natural water with PNA codted naphthalene column has been developed. The ethanol eluting solution was determined by atomic absorption spectrophotometry. The conditions of the preconcentration has been studied systematically and the recover is 95%～105%.
