本文报道了钒-3,5-Br_2-PADAP-DPG-NaBrO_3新极谱催化波体系,确定了测定钒的适宜底液条件,测定钒的线性范围为0.04～18ng/ml,探讨了极谱波性质,本法成功地应用于自来水和矿样中钒的测定。
In this paper, a new polarographic catalytic wave system of vanadium-3, 5-Br 2 -PADAP-DPG-NaBrO 3 has been reported. The optimal conditions for the determination of vanadium were established. The linear range of vanadium was 0.04-18 ng / ml. Nature, this law has been successfully applied to the determination of vanadium in tap water and mineral samples.
