摘要：

A method for the determination of vanadium at trace levels was investigated using air-segmented continuous-flow analysis based on a catalytic reaction with Bindschedler's green leuco base. The detection limit for vanadium was 21 pM and the reproducubility at the 10 nM level was 0.6%. Vanadium in natural waters can be directly determined by this method.
