摘　　要：研究了用ICP AES法快速测定钢中钒和钛,确定了最佳测定条件。在此条件下测定,获得满意结果。钒、钛的检出限分别为0 030μg/g和0 090μg/g;RSD分别为0 82%～3 17%和0 45%～7 47%;回收率分别为94 7%～99 1%和96 0%～98 7%。A rapid method for the determination of vanadium and titanium in steel by ICP-AES is studied. The optimal conditions of the determination are established. Under the conditions, a satisfactory result can be achieved. The detection limits for vanadium and titanium are 0.030 μg/g and 0.090 Kμg/g respectively. The RSDs are 0.82%-3.17% for vanadium and 0.45%-7.47% for titanium. The recoveries are 94.7%-99.1% for vanadium and 96.0%-98.7% for titanium.
