摘　　要：介绍利用双硫腙(D2)作为螯合萃取剂,对水体中痕量钴进行萃取富集,采用基体改进技术由自动进样器注入石墨炉测定水中痕量钴的方法.本法操作简便、价廉、灵敏度和回收率高,加标回收率为97.4%～104.4%,RSD<3.47%.<Abstrcat> The method of determining trace Co(Ⅱ) in water has been introduced by using matrix improvement technology and using Dithizone(D_2) as extraction close of Co(Ⅱ) with GF-AAS. The operation was sample and convenient, and the cost was low. Sensitivity and recovery rate were high, and the recoveries were 97.4%～104.4%,RSD<3.47%.
