摘　　要：建立了一种高杂质铜阳极泥中金量的测定方法,研究了取样量、消解条件以及配料对高杂质铜阳极泥中金量测定的影响。该方法测定结果的相对标准偏差为1.29%~2.35%,加入标准物质回收率为97.8%~100.3%,适合高杂铜阳极泥中金量的准确测定。A determination method for gold content in high impurity copper anode slime was established, the effect of sampling amount, digestion conditions and ingredient on determination on gold content in high impurity copper anode slime was carried out. The relative standard deviation of testing results was 1.29%~2.35%, the recovery rate of added standard substance was 97.8%~100.3%, it is suitable for the accurate determination on gold content in high impurity copper anode slime.
