Determination of vanadium and titanium in steel by ICP-AES

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 μg/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.
