钒的树脂相分光光度法研究

Study on Vanadium by Resin-phase Spectrophotometry

提出了钒-焦性没食子酸体系树脂相分光光度法测定痕量锐的方法。灵敏度高（ε590=5．6×104L·mol－1·cm－1），选择性好．测定范围为0～1．4mg·L－1。实测了天然水中的钒．结果令人满意。

Spectrophotometric method for determination of vanadium was introduced. It's reaction about vanadium on resin phase. In accordance with the Beer's law, the determinationrange is obtained as 0~1.4mg·L-1 of vanadium in natural water with satisfactory results.
